TG Daily reports it's unlikely that Microsoft will continue to offer Windows XP for netbooks for a long time:
The director of netbook PCs in Microsoft's Windows client group, Don Paterson, told The Register in an interview, "We will continue to make Windows XP available for those devices [netbooks], but it doesn't make sense to put marketing effort behind those devices. As much as we make Windows XP available for a year, we won't see it last in the market that long. We will get through the holidays. My gut [feeling] is we will walk away from the holidays and see that it's not worth keeping it in market."
Paterson added that those who "do their homework and understand the value proposition [of Windows 7 Home Premium] will migrate," while those who choose Windows XP are just looking for "absolutely the lowest cost device" or are just resistant to change.
