seriously, people are still crying about looking down at the keyboard, having to reach out and touch the screen, ect.
first off YOU DON'T HAVE TO BUY ONE. it's just like the tablet, if you don't need it or it isn't for you DON'T GET IT. if you dont think a touchscreen is practical, *gasp* don't buy it.
secondly, you don't think apple engineers are asking the same questions everyone is crying about? if its not practical, easy to use, or apple in nature, it won't be released period.
so seriously get off the ledge people.
