It truly is the end of an era. In just under two weeks, Microsoft will follow through with its plan to shutter the Windows Mobile 6.x Marketplace for good. In a cautionary email, Redmond asked that those still using a WM device "install any available updates in advance of the [...] shut-down," scheduled for May 17th. Not all hope is lost for the antiquated mobile operating system, though, as the announcement reminds technology holdouts that application updates can be acquired directly from developers (good luck with that). If you're out on the town this evening having a few drinks with friends, remember to pour one out for Windows Mobile, a true OG smartphone operating system.
