Ask HN: Is it too late for Nokia

I bought a little bit of Nokia stock last year because I agreed, generally, with the adoption of Microsoft's smartphone platform and the stock had already taken a huge hit.

The stock has continued to decline for the last year, and things aren't looking great. Windows Phone 8 is exciting, and there are several Nokia services built into it, but it seems that they've killed off this Lumia line by not extending hardware support of Windows Phone 7 and 7.5.

Do you think I should, as a shareholder, jump off of the burning Nokia? or might there be a turn around coming?
