Apple have a problem...........
1024x768 on the iPad
No it's not wide-screen, and despite what some may say it should be, cutting off the sides of a typical movie to see it full screen is not something that should happen in 2010.
But, they still have a problem with that screen res.
If they did go with Ipad-HD and make the screen res 1920x1080 then all current iPad software coming out over the next 12 to 18 months will scale horribly onto that pixel layout.
Their only option (to keep things looking nice) would be to pixel double it again.
They could go 2048 x 1536 (bit of an odd rez) and still not widescreen.
I really don't know how they will deal with this.
I know many will disagree, but the 1st model was the one to set the aspect ratio, and either they are going to be stuck at 4:3 forever when everyone else brings out wide-screen to make movies look their best, or they are going to have to make a mess later down the line.
Sorry, no, the iPad shouldn't be widescreen. 4:3 is the best compromise for a device that not only plays movies but has to work as a computer too. Those that complain about this haven't thought it through in the same way that people complained about the bezel without realizing that it's kinda necessary in a touchscreen device to have a way to hold the device without touching the screen...
As for people banging on about wanting a 'retina display' in the iPad... are you really saying you expect to see a 2,000 pixel plus display in a 10" form factor at a reasonable cost and without utterly killing batter life? Oh, and with a processor / GPU combo capable of driving such a panel in the iPad form factor? Don't get me wrong, I'd love to see it but I just don't think the technology is there to either a) make the panel at a cheap enough price point or b) allow it to be used without killing the performance and battery life of the iPad.
