What specific concerns did you have with Maemo? Both the N900 and N9 combined "real Linux" with a handful of mass-market apps like Skype and maps, with the N900 having both a hardware keyboard and touchscreen.
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?
