CNN Money and Fortune Brainstorm Tech reported that a new analysis from Piper Jaffray's Gene Munster continued to advise clients to invest in Apple. He pointed to Mac and iPod sales as reasons for optimism.

Wall Street estimated a 22% increase in Mac unit sales for the first quarter of 2010, but January and February numbers show a 39% increase over 2009. The iPod models have turned a corner in sales as well. After sales drops for 16 months in a row, January and February revenue was up 7%.

Munster points out that the increases are skewed somewhat by the fact that the beginning of 2009 was the midst of the recession, so sales were down. In addition, the average selling price of both Macs and iPods is down, meaning people are looking for lower priced models.

DailyTech considers the Mac numbers surprising because of the age of Apple's lineup. "Apple's computer lineup, with the exception of the new i7 iMacs, is rather dated.  The problem is particularly severe in the MacBook Pro series, whose hardware currently trails even drastically cheaper models from competitors like ASUSTek."

There's room for even more optimism considering the future. The iPad launch in April should be a huge shot of revenue, and an iPhone update is expected this summer.
