Unfortunately by giving it away they are pointing to the intention to double down on the Store model where apps are rented and I don't think people will pay for them, not their billion+ desktop customers who are trained and set in the Windows model.
Please someone explain this to me: quite a lot of these users who see the Windows Store as the Big Evil Who Brings The World To The End, in their Android and iOS phones and tablets see the same totally natural and acceptable.
Android: You need to use a Google account, if you need apps you search the Google store and if the app you want to is not free, you pay for it.
Windows 8 and later: You need an MS account but only if you want to use Windows Store, if you need apps you search the Windows store and if the app you want to is not free, you pay for it. The similarities end there: In addition, you can completely forget the store and download / buy desktop apps as in XP or Seven and use them, without any whatsoever account needed.
How is that in Android that is OK although Google tries everything they can to force you to use Google Play, but when Windows offers the Store as an additional feature which you may but are not forced to use, it's The Sign Of The Devil?
I would never use an MS mail app. I use AOL since day 1 and never lost a mail. I can still retrieve my mail from 2007 and need not use any storage space on my machine. Same with Gmail. If I think of all these poor suckers that lost their mail when going from one system to another I think I did the right thing.
Wolfgang, Windows Mail App uses IMAP and Exchange protocols. Both are similar in the way they handle the messages: they are stored on server. Setting up the Mail app in a new Windows 8 or later computer it retrieves all your mail, however old it may be as long as it still exists on server, if you want to. Of course you can only select for instance to show only last weeks messages in the app if you want to and then when you want to get the old ones, too, just change the settings.
