I'm sorry, BlackBerry. I gave up on Research In Motion (NASDAQ:RIMM) too soon. I just felt that we'd have a glut of copycats by now. Instead, Palm (NASDAQ:PALM) is turning to layoffs, Apple (NASDAQ:AAPL) was quick with a $200 price cut on its iPhone, and Nokia (NYSE:NOK) may have some sweet new handsets coming out, but where's the BlackBerry killer?

Really, now. Even the rumor mill chatter of Google (NASDAQ:GOOG) coming out with an ad-supported smartphone turned out to be just an open-source mobile browser, targeting Microsoft (NASDAQ:MSFT) more than the wireless device titans.

This doesn't mean I'm comfortable with Research In Motion's valuation at the moment, but I've been burned betting against the company in the past. It's a good thing I'm watching this week's bout from the fence.

Yes, not all Fools agree. Dave Mock is bullish on Research In Motion. Anders Bylund is bearish. Who's right? Read on and decide for yourself.

Duel on!
