If you are looking for a portable, small, laptop with some power left to spare, I would either go for the Thinkpad T400, Dell Studio 14z, or HP DM3. The Dell Adamo is basically you paying a 70% premium for looks and form factor that isn't that amazing in the first place.
It is def. overpriced. Much like Apple, where one pays extra for a name/casing, the Adamo can be easily outdone by other computers at lower prices. The difference is that the Adamo runs Windows, other computers run Windows...
