If there's a high-tech company on a huge roll right now, it's Research In Motion, which reported that fourth-quarter profits more than doubled, while the number of people using its Blackberry device surpassed one million for the first time. If that wasn't impressive, RIM boosted financial guidance for the first and second quarters of fiscal 2005. After Nokia disappointed the market earlier this week by disclosing its first-quarter sales and earnings will be lower than expected, the wireless industry must have let out of collective sigh of relief with the RIM news. It will be interesting to see how RIM does down the road as Palm's Treo 600, which is a very cool device, starts to gain momentum. My take is that RIM and Treo are now in the market sweetspot – wireless e-mail and Web connectivity – while Nokia is fighting feisty rivals such as Samsung in the telephone market, while struggling to get people excited about its clunky Communicator device.
