Tonight, join the gang for a discussion of Tuesday's hardware announcements; it'll be worth calling in just to hear me and Dave confess our shame at mocking the 5-port power of the Mac mini photo leaks.

To participate on TalkShoe, you can use the browser-only client, or you can also use the classic TalkShoe Pro Java client; however, for maximum fun, you should call in. For the web UI, just click the "TalkShoe Web" button on our profile page at 10 pm Sunday. To call in on regular phone or VOIP lines (take advantange of your free cellphone weekend minutes if you like): dial (724) 444-7444 and enter our talkcast ID, 45077 -- during the call, you can request to talk by keying in *-8. Talk with you then!

Wired's Brian X. Chen writes that Apple will release a new version of the Mac mini at Macworld Expo early next month.

Chen's unnamed source didn't disclose any details about the Mac mini, but Chen offered plenty of specification speculation.

Based on "trends seen in Apple's latest products," Chen expects the new Mac mini to feature a unibody enclosure with speeds and video specs that closely match the new unibody MacBooks.

This follows another rumor of a budget-priced, small-form-factor iPhone that could be announced at the same time. Nilay Patel, of our sister blog Engadget, notes that this may be a reaction to slowing sales numbers, and an overall reticence by consumers to drop large amounts of money on a new computer system.

We'll see next month: The keynote presentation is scheduled for January 6. Macworld Expo typically announces by now if Steve Jobs will give the presentation, but they've been keeping mum about his involvement so far.

Opera Software CEO Jon Stephenson von Tetzchner said in a New York Times interview yesterday that its engineers have developed a version of the Opera web browser that works on the iPhone, but Apple has rejected it for the App Store because it competes with Safari.

This isn't unprecedented: Apple rejected an app called Podcaster possibly because it duplicates functionality in an upcoming version of the iPhone software. Podcaster was (for a time) available via ad-hoc distribution before that, too, was shut down.

Daring Fireball's John Gruber suggests that Apple rejected Opera because the browser included its own JavaScript interpreter, something forbidden by the iPhone SDK developer agreement.

Opera makes two flavors of its mobile web browser: Opera Mini for most mobile phones, BlackBerry, Palm, or Windows Mobile; and Opera Mobile, a more featured version for Symbian and Windows Mobile. A beta version of Opera Mini for Android is also in development.

Update: Gruber used his massive Rolodex over the weekend to determine through an unnamed source that the app may not have even been submitted to the App Store. Huh.

Gizmodo is citing two major European retailers, who have said they are not expecting any more Mac mini shipments from Apple. This could mean one of two things: either a new model is soon to be announced, or the line will be discontinued as early as today's Q4 conference call.

Many people love their Mac minis, turning them into everything from low-cost web servers to roll-your-own DVRs. It was originally intended for switchers who didn't want or need to replace their screen, keyboard or mouse, but wanted the Mac experience.

On Amazon.com, the MacBook continues to be Apple's best-selling computer, followed by the 15-inch MacBook Pro. The Mac mini comes in third, ahead of the 24-inch iMac.

As someone with a family member interested in a Mac mini, this doesn't bode well. What do you think this means? Will Apple have another ultra-low-cost Mac waiting in the wings? Leave us a comment with your predictions.

A recent post at hicksdesign on turning a Mac Mini into a media center is very serendipitous for me, as I'm currently researching options (and buying hardware) to do just that. I've acquired a Mini, a couple of hardware items that I'm trying to decide between and several software solutions that I'm putting to the test.

The post serves well as an update to some of our previous thoughts and takes into account some hardware and software updates. Among other things, the post discusses the decision between the Apple TV and the Mini, the virtues of Front Row 2, external hardware, and some great software tips.

Admittedly, my current solution is the result of hours of hacking and wiring and runs on a PC. I've been itching for a couple of years to make the whole system Mac-based. The hicksdesign post, along with all of my other research, should lead to a system that puts my current HTPC to shame.

Remember the Mini? If you're in a retro mood today, you can pick a 4GB iPod up at sellout.woot for just $79 + $5 S/H. It's not a bad deal on an outdated iPod. In contrast, new 2GB shuffles are selling at Apple for $69 and refurbs 4GB nanos for $129 (including $15 gift cards). TUAW reader Greg writes that it's the perfect iPod for leaving in the car.

A new entry in the Mac category – created by one Dave Veloz for his wife – takes on a Mac Mini and forges a machine that Captain Nemo would be proud to use. The keyboard may be familiar, and the monitor is an evolution of previous works, but the treatment of the Mini and gold lettering in vintage Victorian style brings the full package together in a wonderfully Mac-centric, Steampunk fantasy vision with superb attention to detail. And all that work didn't just sit around looking pretty: the final product was set up at Dave's wedding to display a slideshow of engagement photos.

We at TUAW would like to extend a hearty "hurrah" to Dave for what may be the coolest mod ever to befall a Mini. Maybe even cooler than the Millenium Falcon mod. And yes, that can be taken as an official challenge: show us what you've got!

Thanks Jim!

New units will ship with 1.83 GHz and 2.0 GHz processors and 80 GB and 120 GB drives. You can upgrade to 160 GB hard drives, up to 2GB of RAM, and a slot-loading Dual-Layer supporting super drive (the DL drive is standard with the 2.0 GHz model). You can even pair it with one of those spiffy new keyboards.

Thanks, Carl Trimble.

I'd be sad if Apple discontinued the mini line even if I've had some issues with its design, particularly its lack of dual monitor support. I know that's a strange quibble to have with an otherwise well priced and moderately powerful unit, but it's the single issue that has kept it off the desktop of many of my friends and colleagues.

Thanks, fraserdrew.
