Windows Phone 7.5 vs Android

Both operating systems have their own pros and cons. Android has a massive app store - the Google Play market - so there'll be no shortage of games or utilities. Plus, given the OS's popularity, you are bound to find more tips, tricks and even help in case something goes wrong.

Android is also better for power users who switch between apps all the time, since it offers pure multi-tasking. And with the v4.0 Ice Cream Sandwich update, the platform has gotten a lot more user-friendly as well as good-looking ; but the downside is that the update is not available for many phones yet, and there's no indication of when your device will get it, or whether it will at all. Another persistent problem with Android smartphones is poor battery life.
With Windows Phone 7.5, you get a fantastic interface that, in our opinion, is the best looking smartphone OS right now. Also, phones running on Microsoft's platform generally offer slightly better battery life than competing Android handsets. But there are two major drawbacks as well.

First, the Windows Marketplace app store simply cannot compete with what Android has to offer. You might have to wait for popular apps released on Android to be available on Windows. Second, Microsoft has said that Windows Phone 7.5 handsets won't be upgradable to Windows Phone 8 when it releases later this year; that's a deal-breaker for us, and reason enough not to go in for one.
That said, we would recommend the Samsung Galaxy Ace Plus among the Android smartphones. And if you're still looking at Windows, the Nokia Lumia 710 is your best bet in this price point.
