Wouldnt surprise me to see Microsoft buy it once its gets nearer to collapse (and cheaper).
Yeah, this seems like the logical outcome at this point. Microsoft gets an enormous patent portfolio and huge team of designers and engineers, matches Google's acquisition of Motorola. I'd bet Nokia is in bankruptcy by Christmas.
It's possible they turn it around, but they're in a bad place right now, where their core market is eroding, they're still selling 5 times more Symbian phones than WP phones, and Apollo is right around the corner with a new generation of hardware. There's a decent chance Nokia sells well in the US, but it's probably not enough to stop the hemorrhaging, and the decision to go WP over Android might have lost them Europe.
All that being said, their stock is really, really cheap right now.
Edit: But please don't take the stock advice of strangers on the internet, please. Talk to your financial planner, or do your own research, but buy or sell based on the strength of the company, not your belief, or not, in the company.
