Wait I think both oses can suit the same needs when it comes to modding. What I really like better about Maemo is the user interface is a whole hell of a lot better then Windows Mobile don't get me wrong I like HTC Sense on Windows Mobile it does a very good job but I you dig deep enough you find the rotting guts of Windows Mobile. I really don"t understand why Maemo is more customizable when Windows Mobile allows any amount of to be installed on the System memory or the sdcard when Maemo 5 only lets you install apps on 2gb of memory. After seeing what devs have done with both Windows Mobile and Maemo it kinda make me miss both platforms when the next generation of devices come. Hardspl unlocking in Windows Mobile is rarely needed when it comes to doing stuff like installing custom themes, installing Linux distributions, installing apps on the sdcard, and tethering contrary in Android rooting is usually a difficult process and is required for installing custom themes, installing Linux distributions, installing apps on the sdcard, and tethering. However Windows Phone 7 will the quite the opposite of Windows Mobile classic and Maemo where you will be locked out of sideloading apps, filesystem access, memory cards, custom themes, and tethering. Oh well good bye to good old clunky Windows Mobile and hello to Microsoft iPhone 7.
