Not really sure what you mean comparing BB10 to WinMo 6.5 to WP8. Blackberry is still supporting its old OS, 7.1 now. They actually just released a brand new phone for it. I actually forgot this part about my last post, Blackberry is currently supporting 3 OS's... Lol. I mean, the Playbook OS is all but dead, but it was just updated a month ago or so. So essentially, it took no time for BB to jump from 7 to 10. And also, WP stripped out tons of features from WinMo and is now adding them back. Its typical for any new platform to do this. It takes years to build a matured OS.
In what universe or alternate reality could anyone possibly suggest RIMM/BB took no time to get from BBOS7 to BB10? In the time the BB10 project was underway, the company changed names, has been forced to put itself on the market for buyers, had the OS name changed as a result of litigation, released and killed a tablet, and saw WP7, 7.5, 8, and GDR1 and 2, multiple Google confectionaries, and (I think) IOS 4 - 7.02 (maybe 5 - 7.02). I use the current date since BB10.2 is only a leak and the OS has struggled with bugs, feature holes, and a truly empty app store. When 10.2 is officially released, the OS will finally be at a level of completeness and stability roughly comparable to any other player. WP8 will have seen within one calendar year three significant updates, plus additional OEM firmware improvements. That is far more than Android and IOS, and BB is still working on basic bug fixes to its original release. Just because BB uses a .x designation for basic .0X fixes, does not make them even the equivalent of even Android 4.1, 4.2, and 4.3, which are hardly major changes themselves. How long exactly has Android been on 4.X, and until IOS 7, what were the things that really distinguished the three preceding full version number upgrades? Updates to WP8 have not been perfect but they have certainly not lagged. As far as any statements that they do not doing things like RIMM/BB go, that is really a compliment in the tech industry.
