Do you know the one issue that I desperately wanted to get resolved? Compatibility. Opera Mobile runs on older tablets (I believe v1.5+), and I was afraid that Opera Tablet would drop support for older versions. Don't worry. I was told that if you have Opera Mobile running on an Android tablet, it should also be able to run the new Opera for Tablets.
You might recall that some time ago I said that apps designed for a 5" screen won't scale well to a 9" screen. The older version of Opera running on my Android tablet amply proves me right. Luckily, Opera figured this out and that's why they're doing the new Opera for Tablets.
I'm not an Opera fan, but I can appreciate the changes they made. I can't wait to try it on my tablet. The release date has been announced as Soon.
