They have probably sinked ludicrous amounts of money to Maemo and Harmattan/MeeGo. Trollech/Qt that's a solid piece of it all costed them alone 220 million euros and that's probably a drop in the water they have spent to this whole Qt rounded projects as a whole.

They are still a company.

As for a tablet i have been lusting a Nokia designed tablet running MeeGo for a long time. Would have had great to see Nokia's take on these larger than 7" tablets. It's certain that Nokia will still have a tablet, but i'm totally lost on what OS that could be and when(4 months or 5 years).
Android did not get much of help from the phone side and they got ~40 apps for a 3.0. It would not sound totally out of this world still to have MeeGo tablet along with WP phones from Nokia.

But who knows. I have already pre-ordered Asus Eee pad transformer.
