Love to tinker and tweak your smartphone? Find running beta apps a challenge, not a burden? Then you'll be happy to hear that Nokia's N900 running Maemo 5 is now shipping in the US, a week later than the press release suggested. This Cortex-A8 phone with 32GB of on-board storage is ripe with potential and the perfect holiday gift for grandma as long as she's comfortable dropping into the X Terminal for the occasional "rm -R /home/user/.microfeed" command. It's still listed for $649 unlocked from Nokia direct though that price will be dropping soon enough.
