i love my 3gs iphone (i don't own, nor have i ever owned, any other apple product). not having multitasking on a 3.5 inch screen, on a machine with battery issues already, isn't that big a deal, but if i listened to pandora or lastfm every day, i guess it'd be a bigger deal.
that being said, not having multitasking on a 10 inch screen is inexcusable. i'd rather have a netbook than this.
