Earnings reports and rumors provide plenty of fodder for this week's operating system rundown.
Samsung, Apple fight for #1: Samsung Corp. wasn't about to let Apple Inc. (Nasdaq: AAPL) get all the glory this week. The Android handset maker shipped 95 million smartphones in 2011, according to IHS iSuppli , up 278 percent from 25 million in 2010. Apple, which shipped 37 million iPhones in its explosive first quarter, only shipped 93 million for the year in total, making it a close second. According to iSuppli, it's now a "tight battle for leadership that will continue throughout 2012" between the two device giants. (See Apple: the Numbers Behind the (Huge) Numbers.)
Nokia waits on Windows Phone: Nokia Corp. (NYSE: NOK) is hoping it can pull an Apple and make up for a weak quarter in which it's waiting on its next Windows Phone smartphones with an explosive one to follow. The Finnish handset maker lost US$1.25 billion in the fourth quarter as it works on its transition to its new OS. Nokia did, however, manage to sell more than 1 million Lumia smartphones during the quarter, suggesting there's hope yet. (See Nokia Ends 2011 on a Low.)
