Based on a report from i4u.com, Windows Phone 7 probably has had a rough start so far.

Microsoft has spent $100 million on advertising and who-knows-how-much on buying high-end apps for launch day. They must have been expecting a better launch than that. While those numbers haven’t been confirmed by Redmond, their silence is telling. Steve Ballmer was excited enough about the Kinect’s million sales to make a fancy announcement at the annual shareholder meeting. He also mentioned Windows Phone 7, but all he would say was,

“…it marks the beginning, we think, of a new era in smart phones. The response has been really fantastic,”

But the Microsoft CEO gave no concrete numbers. No sales data. You can bet he would have if those numbers had been worth bragging about.

Some of these sales issues may be due to supply shortages, which have hindered sales in the UK. That said, Windows Phone 7 seems to be doing well on the International market. Both Europe and Australia are reporting “better than expected” sales.

Again, no hard numbers were given. Which really echoes the cause for concern. Especially since Microsoft loves to brag about good numbers. This is really evident when you look at WP7′s app situation.
