Finally, a level-headed review of the Duo
(Full disclosure -- I own one.)
Good job, Reg! Every review of the Duo I read either comes at it as if it were a tablet, and says it's too bulky, or as a laptop and says it's not powerful enough. It's neither.
Yes, the battery is terrible. Yes, it needs video out (at least). Yes, it's a bit awkward to use as a tablet. Yes, you should remove all Dell-branded software before you do anything else with it. Everything other issue mentioned has been a non-issue for me.
There's several different marks that hardware is designed to hit (desktop replacement, laptop, netbook, tablet), and the Duo hits right between several of these. If you think of it as a very nice netbook with a gimmicky screen, it starts to make sense. Also, that touchscreen works in laptop-mode, too, which comes in useful in several cases.
If Dell can address the 4 problems I've mentioned (or just the first 3 -- I'll be removing their software anyway) in the next version, they'll have a real winner.
