Nokia Internet Tablet Generations:
770: Great 1st gen. device with an RS-MMC (SDHC compatible, w/ s/w upgrade) slot.
N800: Gave us a second (full-SD) slot and full-sized the external one.
...But they stole my screen-cover!!! and wrecked the external buttons!
N810: Gave us GPS and daylight-readable screen, and tippy-tap keyboard.
...But they stole one of my SD slots, and shrunk the other!! And hid my d-pad!
N810 WiMAX edition: Gave us ubiquitous-in-certain-select-square-miles broadband!
...But they took the tippy-tap keyboard back, and stole my d-pad with it!!!!!!! (Check the picture -- no keyboard or d-pad visible )
