I received the update last night. I am not a fan of the home page of the app market but I do like everything else after it. I like how it is more organized in when you select an app and want to read the comments, description and other related apps.
Apple doesn't give any return option either.+1
Very nice (showed up today). The 15 minutes is still more than you would get for a BlackBerry app (or at least in the past). You buy it; you own it. I was so impressed with a 24-hour option to return it in the Market for Android ... and took advantage of it from time to time. The 15-minute window isn't much, but it's still better than no window at all.
