Last Friday, Nokia (NYSE: NOK) saw something rare: market-thumping gains!

Once again, takeover talk was the culprit behind the optimism, not Nokia's actual business by any means. Specifically, the rumor was that South Korean conglomerate Samsung was interested in scooping up the Finnish smartphone maker in an expression of self-loathing and masochism.

The idea makes absolutely no sense. I'm pretty sure Sammy is doing just fine on its own, leveraging Google (Nasdaq: GOOG) Android to leapfrog Nokia over the past year to become the No. 1 smartphone vendor in the world, according to IDC's first-quarter figures. Samsung's market share nearly tripled while Nokia's was sliced to nearly a third over the same time, although part of Nokia's loss has also been Apple's (Nasdaq: AAPL) gain.

The iPhone has not been kind to Nokia -- just look what's happened to the gadget maker ever since the original iPhone's launch in 2007.

Ouch. Samsung went ahead and shot down the rumor, telling Reuters, "Such reports are purely speculative and are not true," sending shares back whence they came.

Never one to take "no" for an answer, the market quickly clamored onto the next buyout rumor to satisfy its speculative cravings. This time, our old friend Microkia stopped by for a brief visit just to catch up. It was December the last time it showed its ugly face, and this visit was a tad behind schedule compared with my expectation that we'd say hello again in three months. Better late than never, I suppose.

This time, The Register is saying that Microsoft (Nasdaq: MSFT) was given a peek at the inner workings of Nokia's books to consider a possible deal, and the software giant politely fled the scene after seeing Nokia's private parts. If you ask me, this relationship is a little lacking in the intimacy department.

Consider this gloomy chart directly from Nokia investor relations.

If you think that looks bad, just imagine how it looks from the inside. Sales fell 9% in 2011, gross profit shrank by 12%, and adjusted operating profit plunged 43%. Operating cash flow dropped by 76%, and adjusted earnings per share was cut in half.

Sorry, Nokia. You're destined to go it alone.

Apple's continued decimation of rivals like Nokia is one reason you should buy Apple. The Mac maker still has plenty of upside thanks to ample opportunities in the next phase of the mobile revolution: tablets.
