Installed it on my netbook to try, and it's a shiny, braindead pile of fail. Keeps dropping the network, the video drivers are a lot worse than I had under umbongo.
The interface is wretched, and it's stuffed with tonnes of really terrible default "integrated" clients that cover most protocols really badly, missing loads of features. The default repos are devoid of good alternatives, and it's not immediately obvious how to pop open a terminal to fix things (other than going to virtual tty1, obviously).
So, as a drool-proof vertical platform, it's nowhere near as slick or nice as Android (I'm used to 2.1 with HTC sense, which is surprisingly nice), nor is it any good as a computer interface (I am a debian/umbongo and ex-slackware user, and occasional MacOS and 'doze monkey).
Moreoever, I am disinclined to trust any platform that Nokia have any hand in at all, having being burned by useless crashing series 60 phones, defective software to talk to them, and the unmitigated horror of the Ovi store. Fuck Nokia right in the ear, with bells on.
"Meego" is also an offensively lame name- like something Steve "Uncle Fester" Ballmer might deem "cool". Actually, the faux-quirky cartoons during install, saying "Meego is cool", do look like the sort of corporate dad-dancing branding that brought us "Bing", now I think of it.
Goodness, that was a lot of nerd rage, wasn't it? I should probably have that first coffee off the day. Apologies, everyone.
