If Nokia comes out with anything (pure) MeeGo based, after their switch to Microsoft Windows Phone 7 as their "flagship" OS, who would trust it? I wouldn't... they might change their mind yet again without explanation.
And by now, after the 770, N800, N810, and N900 having basically been treated as nothing more than pet projects with the support for the OS, devices being (understandably) smaller than Nokia's other offerings, it's not another pet project from Nokia I'm after. It's either going to be corporate backed and supported fully or released fully open source with zero closed bits. No in-between for me because I had a N810 with closed bits that never got worked around - not to mention a GPS product where "life membership" was relegated to 2 years - and closed bits on the N900 that will invariably cause problems down the line.
As it stands... a MeeGo device would be better off in the hands of Intel. They've at least stayed behind the product when Nokia didn't. That unwavering support in MeeGo is enough to make me want to buy from anybody else but Nokia at this moment.
