im no apple fanboy by a longshot lol but i can definately see a place for one in my house, my setup is a windows desktop in the bedroom, ubuntu laptop downstairs, and n900 in my pocket. i could use an ipad for the missus to go on the net without callin me every 5 mins cause theres "somethin wrong with the computer" it makes a great photo frame and browser and also for my kids to watch films on. basically it would get everyone off the my computers which they cant really use properly for the little tasks, which is all they do, and also it looks great doin those little tasks, and there are, among the piles of crap, some quite good apps.
thing is its not a proper computer by a longshot, but most people dont need and cant maintain a fullblown computer. so its great for them to have it all simplified and lookin great without the fuss.
