Research In Motion (NASDAQ: RIMM) has a great customer following and a nearly unbeatable lead in the mobile email market with its BlackBerry product line. Still, the competition is lining up to steal market share (most notably, Microsoft). With RIM reporting Q3 results today, how will the wireless handset and email addiction company perform?

Analyst estimates peg the handset maker's EPS at $0.62, and the company will most likely hit that number (Think not? Sound off in comments). Still, market pundits worry that the huge slowdown and massive losses in the financial sector due to subprime mortgage woes may stunt demand for RIM's ubiquitous portable email devices. Although that may be true, will the impact be that large? Unless massive layoffs occur in the financial industry, all those BlackBerries will still be humming with incoming emails.

Still, RIM's stock gain ride of 12% in the prior three months before December have now been offset a little by a decline of 6.5% in the last four weeks on worries of a sales slowdown as referenced above. Still, for the Q3 period, the company is set to beat expectations of $1.65 billion in revenue and $0.62 in earnings per share. And compared to the year-ago quarter figures of $835 million in revenue and $0.31 earnings per share, that's not bad for YoY gains.
