Additional sources suggest cameras on iPad 2

What - on - Earth will a camera in the back of an iPad be useful for? There may have been people falling over themselves to be negative about the iPad at launch to protect their existing markets and market shares, and one of the things they claim is missing that is stopping them buy an iPad might very well be a camera - but does anyone really think these PC lovers will actually go out and buy anything from Apple? Not on your life.

Personally I cannot imagine an instance when a camera on the back would be useful.

Who cares about screen resolution when you are holding something only a few feet from your face? If you can tell the difference between a 720p and 1080i image on a 9 inch screen 3 feet away from your face then you have some incredible vision. My vote would be to have an aspect ratio that hasn't been dead for nearly 12 years. I understand a 4:3 screen is great for surfing, but watching a HD movie on a 4:3 tablet is simply horrible. I could care less about cameras or being slimmer; just give me an aspect ratio that I can watch movies and shows without feeling it is on a CRT from 1995. Oh and way better Wifi. Since day 1 my iPad has had a horrible wifi experience. Case in point I just got back from Houston where in the hotel my iPhone 3GS found 5+ wifi networks, but my iPad couldn't even get 1. The wifi signal constantly drops and is very slow. Same with my moms 3G and sisters Wifi only. Seems odd that 3 out of the 4 people I know that own an iPad all have the same problems.

"Retina display" is just a marketing term. And since iPad is typically held at longer viewing distance than iPhone or iPod touch, Apple can easily get away with lower PPI and still call dub Retina display.

As Mack said, double scaling is the approach Apple will take with iPad, as it is easiest and least process intensive way to bring backward compatibility. On 9.7" display, that would be 264 PPI at 2048x1536, which is still higher than most high-resolution Android and Windows 7 phones.

That said, processing full 2048x1536 graphics, especially 3D for games, will require good deal of video memory and beefier GPU. And I suspect such LCD display will cost pretty pennies. So I would be very surprised to see such display on iPad 2... more likely in 2 to 3 years.

" Just powering such a thing would be difficult to say the least."

I find that line distasteful, everyone knows Apple performs miracles when it comes to power usage. And finding ways to blame Adobe and such for shortfalls.

Retina display? I guess just double the resolutions (1024*768 -> 2048*1536)? That sounds more logical as everything can be pixel-by-pixel scaling like iPhone.

...too good to be true (as of today)?
