Microsoft has announced some details of an upcoming new Windows store that will let you download applications for desktops, laptops, tablet, and phones. The store will offer developers an 80% cut of each download, provided the app earns more than $25,000 in sales, which is more lucrative than many other app stores offer. Otherwise, devs get the same 70% cut that Apple and Google offer. Apps will start at $1.49 (as opposed to 99 cents in Apple’s store) and some will be offered free as well.
