I'd be all for a harddrive in the N900... just make sure the OS boots off of internal memory and that the HDD is smart enough to stop spinning when not in use. Perfect for saving juice when need be.

Or back to my original stance of releasing battery powered hardware modules that work either via bluetooth or USB. (Want storage? Plug it in. Want a webcam? Plug it in. Don't want either? You'll still buy the base device. Everyone's happy.)

... of course that idea won't make it into the N900 which, by my calculations, should be released in two weeks featuring the amazing improvement of ultrablue LEDs under the buttons.
