It is still the same old 8MP/F2,4 sensor lens unit from Sony that is used in Sony (Ericsson) phones for years now. Don't know why this is worth an article here.
migus: It's still far from 'retina' (326dpi) but much improved display. I hoped for AMOLED w/ deeper black than the typical milky-gray IPS... Not convinced yet that i ever need an iPad, though one could use it for photos - as an expensive digital frame :-).
My main interest for such toys would be in maps/GPS and PDF papers/magazines... basically a hi-res reader. Again, i'd rather save my eyes w/ e-ink or a friendlier display (not backlit). Mitch
Amoled? Yeah, great black - but green-grey white. ;)
