Is Microsoft Merging Windows Phone 7 and Windows 8 Desktop OS and How?
Looks like MS is preparing to merge Windows Phone 7 and Windows 8, but they're not sure how to do it yet. I heard some rumours they're trying to run run Windows 8 on some ARM phone hardware. Windows Phone 7 is still based on Windows CE, which was cut down to fit on year 2000-era ARM devices and hasn't been beefed up that much since then, while Android and iOS are based on Unix cores more comparable to Windows 7 or Windows 8 for desktops. Windows CE is still popular for vertical-market small-screen data entry and device controls (on MS campus, desktop phones and room reservation gadgets are based on CE) which have not yet switched to either iOS or Android. ARM devices now are running as much or more powerful hardware as Intel PCs were in the year 2000 especially for video and graphics.
The first decent PDA was palm when CE was based on "palmtop" very-small clamshell devices which succeeded the tiny DOS-based HP 100LX and 200LX, but lost steam once Microsoft essentially took the spirit of Palm into the "pocket pc" and made phones out of it. The pocket pc phones could do much of what you can do with the iPhone today, except not as well, and not as easy to use. It used stylus, not finger gesture as was essentially a shrunk down desktop user interface, where iPhone re-thought out how to do a gui with fingers and gestures.
Apple so far has had not that much commonality between Mac and iOS other than Cocoa UI and the offbeat objective C which make it really hard to port to either WP7 (C# Silverlight XAML) or Android (Java)
but here's the meat:
Earlier this year, there were some major leaks as to what Microsoft was planning to deliver as part of the feature set for the next version of the Windows Phone OS. Among the planned features:
