Mary Jo Foley talks about the release date of Windows 7 in her latest blog. A lot of what she says makes good sense. Personally I can't see 7 arriving in 2009. I suspect the most likely scenario is a delay influenced release in mid-2010. I also can't see Windows 7 being massively different from Windows Vista. The new kernel, an enhanced security model and much closer ties to the Windows Live Suite will be the most notable differences but I suspect the UI and the experience in general will not change substantially. I look forward to seeing the first beta release in the last few months of 2008 and will be keeping close tabs on Windows 7 news as it becomes available.
