colinneagle writes "Microsoft has promised that cross-platform development across the 8s – from Windows 8 on a desktop to Windows Phone 8 – will be a simple matter, but that's still not enough to get some developers moving on Windows Phone 8 support. The Windows Phone platform has made a remarkable recovery since its reset with version 7. Since then, WP7 has grown to 100,000 apps. But that pales in comparison to the 675,000 in Google Play and 700,000 in the Apple App Store. Granted, there's a ton of redundancy – how many weather or newsfeed apps does one person need? – but it points to availability and developer support. A report from VentureBeat points out what should be obvious: that while developers like Windows 8, they aren't as excited about Windows Phone 8 software because they have already made huge investments in other platforms and don't want to support another platform. A survey by IDC and Appcelerator found 78% of Android developers were 'very interested' in programming for Android smartphones, a slight drop from the 83% in a prior survey. Interest in the iPhone and iPad remained undiminished, with 89% and 88% interest, respectively."
