Start/All Programs/Send feedback. The more people ask the more likely they'll take notice.
Presently 7 is still in beta form. As I remember correctly WM was out of commission in Vista when that was in beta there particularly the RC1 release. If you look closely you can still see the WM folder and files in the Program Files directory in 7 too.
Until 7 is finalized or the next beta release is seen you can use T-Bird or Live Mail.
Thunderbird for life. If omitting mail makes room for more important features I'm all for it. I'd just uninstall any mail client anyways.
I decided to give Thunderbird a try and i like it a lot, so have also installed it on my XP partition.
