This boggles my mind. I have an iPhone 4, which I love. I bought an iPad 2 recently, and I can't tell the difference in screen resolutions. Is it because I hold the devices at difference distances from my eyes? Likely. But never once, not for a second, have the words "low res" entered my thoughts in regard to the iPad.
It's not low resolution (actually it's slightly higher resolution than the 3.5" iOS devices). The only thing I think it matters for personally is if you hold it close to your face and read on it for a long time. That's why I'd like to see a 4x resolution eInk screen, since I don't really want to read on an iPad anyway.
Just please don't call it iPad "HD". HD stands for everything and nothing. Specifically, it's supposed to mean a group of low resolutions used on television. The iPad's current screen resolution is 1024 x 768, which is already higher than "HD".
Eh? No it's not. "HD" doesn't necessarily mean anything in and of itself, but HDTV does. Specifically it's a TV with an ATSC tuner and support for at least 480i/p, 720p, and 1080i. Anything labeled an "HDTV" is higher resolution than an iPad, though frankly I don't think calling the current iPad "HD" is bad...for a 10" screen it is high resolution, and heck, 640x480's been called high resolution back 15 years ago when it was 4x the res of the more typical 320x240 console games were rendered at.
If you make the iPad's screen "Retina" resolution, you'll instantly get waaaay more pixels, which doesn't even compare to HD.
That "Retina" thing isn't a resolution, it's (if anything) a pixel density. The iPad, which has a LOWER resolution than 720p HDTVs already has a higher resolution than the "retina" display in the 3.5" devices, they're just crammed closer together.
Anyway, I don't think it would be very Apple to have a low-resolution and high-resolution version of the iPad. Even if they did do it, it would only be because they can't get the retina screen price low enough, so you'd only have two models for like a year, after which only the retina version would remain.
I don't see how it is or isn't "Apple like", and seems like a reasonable move if they don't have access to enough 4x resolution screens, or they just cost to much. Seems like a good idea to me, if handled right.
