Gene Munster, a Piper Jaffray analyst, on Business Insider:
As in the smartphone market currently, we believe Googleâ€™s Android OS will power the stiffest competition to Appleâ€™s iPad. Long term, we believe Android could surpass the iPad in tablet market share due to devices from numerous manufacturers.
From what I’ve seen of Windows Phone 7, if Microsoft decides to re-enter the tablet market using its WP7 OS I think it will give serious competition not to Apple but to Android. The same hardware guys are in both camps and it seems Microsoft is doing a much better job of providing a good, consistent experience. via Wired
