Why do you want such coarse pixels? That's worse than even the 770/N800/N810 had; at a time when the competition is finally catching up in PPI, it's no time for Nokia to go two steps backwards.

IMO it should be 1280x800 5.6" (like the screen in my Fujitsu U820, only this would be transflective -- a screen to kill for!), but if you don't want to go over 5" at least push for 1024x600!

Otherwise -- yes, I'd definitely go for a larger (and higher resolution) non-phone tablet. Would prefer it has built-in 3G/4G that actually works with a reasonable provider where I live, but it looks like AT&T took that off the table.

But I can't really see any reason to suspect that Nokia will make thay device at all, let alone before anyone other MeeGo device makers do.
