>I have heard of (not actually experienced as I do not have an Android phone) programs on the Android Market stating When you open the market on a device it is pre-filtered to apps that work on your handset with your features, in your region, etc. Users don't have to read through and sigh at disclaimers. Apps can even pre-filter by your screen size, whether you have a GPS, and so on. The situation with Android is very similar to the Windows landscape: Lots of apps work perfectly fine back to Windows XP or before. Yet occasionally an app demands something particular on the newer variants so it becomes, for instance, Windows Vista+. Same idea with Android. That's just life of a quickly evolving ecosystem, and they've managed it well. And remarkably many of the improvements have been ecosystem enhancements that benefit even apps target obsolete versions. The truth is that even today the platform API was so robust back on 1.6 (that was really the pivot point) that brand new apps still primarily target it.
