Along with today's big Microsoft Office for iPad announcement comes news of a special promotion offering a year's free Office 365 access to iPad owners. There are a couple of caveats, however, which include limited availability and the small detail that you need to go to a Microsoft retail store to claim it. ZDNet:

To promote the big launch, Microsoft is offering a one-year Office 365 subscription to the first 50 customers who bring an iPad into a Microsoft store. There aren't many Microsoft stores, so if your lucky enough to have one nearby and see iPad toting folks in your local store you know why.

So, if you live near a Microsoft store, grab your iPad and get down there first thing in the morning. The promotion starts tomorrow, Friday March 28, and runs for three days only. But with only 50 per store, they probably won't be around too long. Just don't forget your iPad!
