> costs on the order of a thousand dollars
Weasel words. Base model iPad 2 is $499.
> throws away 30 years of office app development
Don't care. Don't use Office or any competitor. Do not need it, do not want it.
> can't play a dvd
Don't need it to. My iPad has 32gig of storage on it. Right now I have seasons 3 and 4 of the Venture Brothers on there, as well as a few movies for my kids. If that's not enough I can stream stuff from my media server, or from Netflix.
DVDs are a dead storage medium.
> can't store more than a couple dozen gigs
So what? It's not a file server. It's a tablet. It has more than enough storage to do the job. And as mentioned before, streaming options are also available.
> doesn't allow installation of different OSs
So what? What if you don't care about installing different OSes?
> runs anemic, "power-friendly" processors
Powerful enough to run Lego Harry Potter, watch a movie, or anything else I want to do with it. What are you prevented from doing?
> can't multitask well
Same question: what are you prevented from doing? It polls for new emails in the background, if I get an IM I'm notified, etc., etc. What's your bitch?
