Software. It doesn't matter if it's for a Mac or for an iPhone. There are certain qualities we just love, that make an app really stand out to us. As a rough approximation, we call it "Attention to Detail" but there's a lot more going on than just looking at tiny details. It's about understanding the user, what he or she wants from the app and needs it to do and how the realities of being humans with weak eyes, large fingers, and bad memory affect the way software gets designed. I asked my TUAW colleagues to share their thoughts on what makes a good app.

Brett Terpstra loves apps that are designed with a unique look but that use familiar controls. As a design philosophy, his ideal applications are both easy to use and fun to look at. Delicious, if you will. Cookie-cutter app elements may be great for prototyping an application's infrastructure but to him an app that really stands out has a unique visual voice.

He really loves Tweetie 2's ability to refresh your Twitter stream by scrolling to the top (with a tap on the title bar, of course), then pulling down and letting go. It's non-standard, but so intuitive that it should be. That's the kind of attention to detail that makes him feel warm inside.

For me, it's all about putting yourself into the mindset of the user. Were features put in place because they need to be there or because the developer thought it would be cool? Is the developer really understanding how real people might use the app? Take the iPhone. Is there a switch that lets you disable autorotation when you're using a game while lying on a couch or in bed? Because that's how real users use real games. And if the developer hasn't thought about details like this, they haven't hit that design sweet spot of matching real world needs against programming limitations.

Chris Rawson loves well-designed icons. They should give you some indication of what the app does, so you can launch it with barely a glance. Want to use multi-touch controls? Make sure those controls are intuitive and that they provide an innovative use of the technology. In his opinion, Convertbot is a great example.

Remembering already-set preferences is another hobbyhorse. Take iPhone apps that connect with the Mac over Wi-Fi for example. A brain-dead simple initial setup should be followed by only needing to push a single button (if that) to connect on all subsequent connections. And as for a finishing touch, he feels that well-polished graphics shouldn't look like something squeezed out over a single afternoon by someone with no artistic skill whatsoever.

Well designed, easy to follow instructions are key for David Winograd. In the best of all possible worlds those instructions should even include user interaction, whether via Q&A or by modeling, to make sure the key points get through to the user. In his opinion, Irene's Spirit has the best tutorial he's ever seen in an iPhone app. If the app were as good as the tutorial, the world would probably implode.

These are just a few key points from our team. Add yours to the comments below. What are the key elements that make an application, whether for Mac or iPhone or any other platform, shine for you?

When faced with the dilemma of upgrading my iBook G4 in June, I started looking for a replacement that would have the same performance as my Intel iMac. I decided upon getting a MacBook Pro 15". With money in hand, I eagerly clicked the "buy now" button on Apple's website. Little did I know that I would be trading in my MacBook Pro more than 6 times over the next 2 months.

I received my first MacBook Pro, and it was beautiful. I loved everything about it. However, after 2 weeks of use, I started noticing the screen striping symptom that others before me have noted. This problem usually occurred after charging the computer from a half-filled battery and unplugging the MagSafe power cable. I didn't think anything of this problem, since it only happened once or twice. After another week of use, the striping problem started becoming an everyday part of charging the computer. I called Apple and even emailed them the picture that you see above (minus the additional note) -- they did nothing and said it was a "software glitch."

The first MacBook Pro did have another problem: When I went to check my email one day, every program would crash repeatedly. I immediately ran the Apple hardware test (AHT) to find out what was going on. As any unlucky person (me) would have it, the memory sticks were dead. I called AppleCare, told them all of the problems I was having and then told them about the AHT results. They set up a replacement order since I was having hardware problems within the first month of ownership.

If you encode your own video for watching on various devices and you're looking to save every last MB on your iPhone, it could be worth your time to re-encode at least some of your larger files with more conservative settings. While I, for example, have been copying the iTunes Store's settings and encoding my DVD movies at full dimensions and about 1500 Kbps to really let H.264 shine, the truth is you don't need anywhere near that much data to watch quality video on an iPhone's display. By re-encoding your videos and perhaps keeping them in a special iPhone playlist for synching, you can bring even more of your favorite videos with you in a fraction of the space. Unfortunately, you can't re-encode videos you've purchased from the iTunes Store because of the DRM. This how-to primarily applies to video you download from the web or encode yourself from DVD movies and other sources.

To keep things simple, I'll use Blade Runner as our encoding guinea pig (which runs a length of 1:56) and Handbrake for all the encoding. Following are a few sample screenshots of how far you can compress a movie, along with the settings you can use in apps like Handbrake and TUAW favorite VisualHub to try this out for yourself.

Peter Svensson of the Associated Press likes the look of Apple TV as a gadget but declared that its video output came up short. "It's as if Apple had introduced an iPod that sounded like a cassette player," he writes. Svensson downloaded a copy of Pirates of the Caribbean from iTunes and declared it "barely watchable".

The article is a bit hazy about testing details, but I'm pretty sure Svensson neither tried watching any High Def content on Apple TV nor did he compare the same data files on both units. Should he blame Apple TV hardware when iTunes compression might have been at fault for his viewing experience? Perhaps a little. Given the tight bond between Apple TV and iTunes, Apple does have to stand behind its current library of video data.

Gundeep Hora at CoolTechZone has taken a critical eye to what some consider are Apple's recent and rocky 1st generation product launches. The article utilizes two examples - the iPod nano scratch issue and MacBook heat complaints - to illustrate what Gundeep argues is Apple's faulty process of releasing products and then reacting to serious flaws when the public outcry spreads across enough blogs and petition sites.

Whether you're already hastily typing a comment to flame Gundeep or you have one of those aforementioned petitions already open in a separate tab, Gundeep has written an interesting piece that I think could strike a deeper chord if he used a find/replace command to swap the word 'Apple' with 'the computing industry as a whole'. Similar criticism of Apple's 1st generation production quality crops up on the web every couple of months like clockwork, and I think it's because there is an unusually high level of expectation surrounding their products. I'm not saying Gundeep's criticism is misplaced; quite the contrary: my first Mac ever was the 1st generation of 12" PowerBooks (867 MHz baby!) and I had to go through four of them to get one that didn't overheat or have a hard drive that choked itself to death within hours of bringing it home. To make matters worse, the Apple Store, including its snotty manager, treated me only slightly better than that sticky stuff you try to scrape off the bottom of your shoe. My next Mac experience was the 1st gen 15" Aluminum PowerBook that was a part of the 'white spots' debacle - case in point: I feel Gundeep's pain, but Apple isn't the only computer and electronics company to exhibit these kinds of mass production complications. Other computer makers have had to recall batteries and entire batches of one computer model or another. Dell recently had to replace some faulty displays, and I can't remember which mobile phone company's batteries are exploding this week.

To wrap this all up: Apple sets the bar high with their unique design and flashy marketing, and because of that, I think their customers and the media at large simply hop on board for the honeymoon each and every time the company whips out a shiny new toy. Criticism like Gundeep's seems to appear when the fantasy inevitably hits speed-bumps that are simple facts of life and mass production. In the end Apple is a company, like any other, that is susceptible to hardware defects, firmware botches and software hiccups. Then the conversation turns to products, quality and accountability of the industry as a whole - but I think that discussion might be better suited for a different post. Granted, none of these issues are any fun when you're the one stuck with the bad apple (yes, a pun), but sensationalizing the situation isn't going to solve anything. Keeping a level head, however, and understanding that 1st gen hardware can sometimes be a gamble - no matter who it's from - just might save a few headaches, and perhaps then you won't need to sign that petition after all.
