Today in Mobile

Microsoft’s busy week continued today as it showcased Windows Phone 8, a new-and-improved version of its mobile operating system set for launch this fall. There’s a lot to like about the upgrade, including dual- and quad-core support, NFC, and a new Wallet hub; and Mary Jo Foley notes that Windows Phone 8 finally gets a real Windows “core.”┬áBut while some of those features will be included in Windows Phone 7.8, Microsoft will not be offering the full-blown upgrade to existing handsets, as The Verge notes here. Most existing users probably won’t mind — indeed, most won’t even know — but if I just inked a two-year contract for the “flagship” Nokia Lumia 900 I’m not thrilled with that decision.
