Unsurprisingly given yesterday's announcement that the Windows Live Search client will be called Windows Live Search Center, Mail Desktop is to follow suit and become Windows Live Mail Center.
Ignoring the fact that the spelling is americanised and will doubtlessly annoy millions of non-US users, the name doesn't describe the function of the product nearly as well as those of Search Center and Safety Center, despite their blandness. Maybe keeping users unaware of the new RSS integration is a blessing in disguise though; much like Live.com some serious work needs to be done turning these products into usable rss aggregators.
In related news, the offical name for the Windows Live Search client has also been revealed to be "Windows Live Search Center". Registration for the beta is now open on Microsoft's web site.
