Microsoft chief operating officer Kevin Turner recently talked about netbook and claimed that retailers experiencing higher return rates as compare to MS-Windows operating systems:

And the reason that we were able to make so much traction – because this is the first real test of the value of Windows – the reason we were able to make so much traction on this particular space is because we went to retailers and said, “Hey, what are your return rates on these Linux netbooks that you are getting?” And they said, “Oh, gosh, they’re, like, four or five times higher than what we’re seeing on other PCs that have Windows.” I said, “Exactly.” So let’s do the TCO story. Let’s talk to customers. And you can’t find a retailer – I challenge you to find a retailer who wants to sell Linux on these netbooks, because the returns are bad. The customer complaints are bad. And our ability to really showcase the value proposition with Windows has never been greater and was never tested more than it was with this particular product. But we’ve made great progress there, but the up-sell opportunities with Windows 7, because it runs so well on these low-end laptops, is going to be tremendous for us.
