I find the ppi of the n900 already on the border of being usable for desktop apps, 720p on 4.5" would be too small for me. But yes, it would have advantages regarding windows/toolbars not fitting the screen etc. But as you said, it's probably not the best phone for desktop apps anyway, pitty it doesn't have a digitizer like the Samsung Notes - but that would mean asking way too much anyway. I think all in all it's quite decent for the price they ask. Maybe it was a mistake to set this pricepoint, n900 & n9 sold for much more initially, and people bought them. OTOH, they shurely know the market better than we do.
