Actually I've been thinking the same for a while, but for slightly different reasons.redscull said:If not retina, how about a higher resolution? I'd like to see 1280x960, assuming Apple is unwilling to budge on delivering a widescreen aspect ratio. 1280x960 could run iPhone 4 resolution apps with a nice pixel-to-pixel unscaled ratio while minimizing the pixels wasted to black bars. It would also make the screen perfectly display 720p HD video with no scaling and minimized black bar wastage.
Actually, I don't know why that wasn't the iPad's resolution in the first place. 1024x768 just seems so bizarre. It's an ancient res. It has nothing in common with the iPhone's res, the new iPhone 4's res, or HD movie resolutions. No matter what it does, it has to scale. Wouldn't all that scaling chew up more CPU than just supporting 1280x960 natively?
Do you remember how the iPad existed as a mythical thing for an unusually long time - it was rumoured, everyone was pretty sure for ages that Apple was working on it, but month after month there was no announcement of the product from Apple. I think that Apple were desperately trying to launch at 1280 x 960 and were probably trying to source the panel at a cost that let them hit their launch pricing and/or trying to squeeze a bit more performance out of the hardware/software to get a satisfactory user experience. Eventually they decided that they couldn't hold off the launch any longer and had to go with a lower resolution for the first product for either cost or performance reasons or both.
I'll take your word on your arguments for 1280 x 960 for HD video, I'm not very knowledgeable on that. I'm actually not so sure on the scaling of old apps. If all the decent iPhone apps update to iPhone 4 retina display then those would render quite nicely on the existing 1024 x 768 screen with no scaling and reasonably acceptable black bars.
The reason I think that Apple really, really wanted to be able to launch at 1280 x 960 is because they do want to switch to a retina display on the iPad as soon as the technology is there to do that (yes, my earlier post a few minutes ago was a joke!) and the ideal way to do that is how it was done with the iPhone, i.e. a doubling of the horizontal and vertical resolution to give a perfect 1 to 4 pixel conversion. Unfortunately doubling the figures for the 1024 x 768 screen doesn't give a > 300 ppi iPad screen whereas doubling a 1280 x 960 does give a pip figure that is very comparable with the iPhone 4 figure (I did do the arithmetic but I can't remember the exact number now).
If Apple really do believe that they need to get to a > 300 ppi figure for the "retina display" version of the iPad (whenever that happens) then at some point they will need to make a resolution change that isn't a perfect 1 to 4 mapping so that will be disruptive to existing apps and so I can see a case for Apple wanting to do that sooner rather than later while there are fewer apps that will be impacted which would lead to a shift to 1280 x 960 in the next revision.
