Dell's foray into this new size territory without defining its goals (beyond hoping to sell a lot, which should never be the only goal) seems kinda silly.
With the iPad, SJ/Apple started with a clean piece of paper and asked what does the 3.5" smart phone platform do passably well but not brilliantly?
The answer was a very short list: Books, Movies, Surfing the web, for which they found 10 inches the perfect form factor (With IPad2, I've little doubt we'll see videoconferencing as an additional feature. They'll test drive the concept on the the 4G phone and could well add it in January)
Instead of trying to be a big Phone and a small iPad, Dell should ask, what does the iPad NOT do well? Gaming––I'm not a gamer, but I'd think that 10" is too big, and end-user service delivery Ã* la UPS, FedEx, pizza delivery, in-store sales, etc. It's hard to guess the exact size of that market, but one would think a few million could be sold IF THEY ACTUALLY TARGETED THAT MARKET. As I see it, 5" is pointless if Dell is trying to sell it without clear goals of their intended user
