While your argument might be correct the market perception at a whole is much more complex. N900 does have a full Qwerty slide out keyboard. This adds in weight and size. One could have said the same about Nokia Communicator, and these certainly had their place in the market. We call the form factor koelkast ('fridge') here, btw. I'd say the USB port fiasco is more indicative of this, but that was found out after release. Again, thats speaking in absolutes. This one was relatively more targeted at the masses, and that was according to plan. Remember corporations often use Linux and open source as R&D playground.
