WOW... quoted on the main page! Thanks Daniel. Just waiting to be proven wrong on everything!
With regard to no Data Sense (on Telus anyway) I find that the Telus site itself does a good, or maybe just adequate job of reporting data usage. It obviously doesn't show app data usage but it does break it down into daily usage so you can probably make an educated guess. You can also set your Telus account to send you txt msg warnings as you approach your monthy limit. So, there is that.
I was just out walking the dog in the woods and took a few snapshots...the camera, as reported, seemed quicker to activate via the shutter button and quicker in terms of auto-focus and capure too. I'm gonna say at some point Samsung has vastly improved image stabilizing cause my 9 1/2 month-old pooch did not stop moving and all the photos are quite acceptably clear and crisp. No blur at all.
Finally, as far as other storage goes, I started the install process with about 1.3 GB of free space. When I was "waiting" at the Preparing to install 100% stage I checked and I had 2.9 GB of space. As of right now, having only added a handful of photos I currently have 4.61 GB. So something has definitely changed...and so far it's a change for the better.
