Normally I would agree; however after seeing how the prior Maemo iterations were dropped, the closed bits are still closed for the most part; I can't recall a time I can't just install something else on a desktop. I just re-appropriated four older Dell P3 Win2k machines with Ubuntu and it's relatively fast and without many issues. The N900, or more importantly to me, the N810 can't say that will happen with all of the bits usable. Not unless I'm missing something.
They're maemo and MeeGo... "Meamo!" sounds like what Zorro would say to catherine zeta jones... after she slaps him for looking at her dirtily...
