Edit: and by the time Maemo was actually running on a _phone_ it was head-to-head against iOS and WebOS. I think you could actually make a good case for WebOS being the greatest ever, but compared to those two Maemo was awful.
Can't touch anything, touch targets are all too small, so you are forced to use the stylus. Visually it looks like the love child of BeOS and KDE. can't tell from a static screenshot but everything was unbelievably slow.
That looks decent.
Maemo was shit compared to a Palm Pilot.
On the other hand, having an ACTUAL Linux command line with ACTUAL root and an ACTUAL keyboard was worth gold, and still sorely missed today.
Maybe IOs is more forgiving. But how would a terminal emulator help?
N900 was released in 2009.
iOS was leaps and bounds better even at 2007 in the original iPhone introduction. Heck, even Android was better than Maemo in 2009.
Well, that pretty much disqualifies any further point.
