Verizon's Droid Incredible is getting a software upgrade over the air (OTA) in a few days bringing V CAST App Store. Yes you will still be able to access the Android Market apps but "WHY" comes to mind. The difference is you will be able to purchase apps directly and the customers will see these charges in the monthly bill. With the difficulties in selling apps in Android Market, Perhaps developers will find this to be a better way.
