I'd be happy with the above 7 upgrades, especially since most apps were developed with AIR. I'd even settle with just a Browser upgrade, as it's the only app outside of messages that keeps this tablet relevant. Our tablet is too unreliable to be used as a business tool, so lets update the consumer applications, and move on.
