WMExperts has a big rundown on all the goodies planned for Windows Mobile 7, including that it might be called simply “Seven.”
I’m not sure if that’s something they heard, or if the Experts are just using that as a placeholder, but as one commenter on jkOnTheRun has already pointed out, it’s not a great name for search engines (though I’m sure they could get top ranking in Bing). Also, it strikes me as odd that Microsoft would break the Windows branding for a name that will be obsolete with the next version.
Aside from that, they have a good rundown of the supposed Business and Media versions and info on the LG Apollo and HTC Obsessions, reportedly the first phones to run Seven. The big question for me is whether they’ll run with what they did with Zune 2.0, at least on the Media version, and/or let the Danger guys cut loose. I’m an iPhone/iPod guy, but that Zune UI is beautiful. They need something that good or better to fight back against the newer, sleeker operating systems.
