Earnings reports came out today, and our two local tech titans took quite divergent paths. Just like last quarter, Amazon rode its low-margin model (recession-friendly in bricks-and-mortar businesses, too) to a healthy profit, earning $.41 a share (vs. $.34 a share in last year’s first quarter). The company attributed the rise in part to the hot-selling Kindle. What’s more, it may even see its hand strengthened by the Apple’s greedy ways. Though it’ll still probably be too cool to attend its own groundbreakings.Meanwhile, across the lake, Microsoft saw its first quarter-over-quarter loss in 23 years, earning $2.96 a share (vs. $4.32 a share for the first quarter last year). The lion’s share of its revenue comes from the Windows operating system, and with PC sales down and Vista’s bad reviews and tightening corporate budgets leading businesses to hold off on upgrades until Windows 7, the company took quite a hit. It also lost money in its Entertainment and Devices Division, home of the coveted Zune.
