Microsoft (NASDAQ:MSFT) is reaching new 52-week highs this week -- highs it hasn't reached since the dotcom boom in 2000. But even at these levels, Fool contributor Daniel Sparks thinks the company could be a buy.

Given a recent comment from a Microsoft executive that it is renewing its efforts for Office for Mac development, combined with a new report from Reuters that the company will finally launch Office for iPad this week, the company's new strategy under recently appointed CEO Satya Nadella is becoming clear: The software giant looks poised to pursue a cross-platform strategy. 

As Daniel explains in the video below, if Microsoft does unveil a solid cross-platform strategy when it launches Office for iPad later this month, its long-term story may finally be compelling enough to garner greater investor interest.
