I'm still banging away a full BlackBerry Torch 9810 review for you all but when it comes down to it, the changes that have been implemented on the BlackBerry Torch 9810 can really be summed up in about 10 minutes (Though, I did go over a bit). As such, I went ahead and did up the above video for you all. It explains some of the most significant changes within the Torch 9810 so that if you're an already existing Torch 9800 owner, you can decide whether or not the Torch 9810 is a viable upgrade.
Personally, I think if you're a Torch 9800 owner and love everything about the form factor, there is no reason for you not to go ahead and grab the Torch 9810. It does bring some powerful changes to the device, and will certainly meet your needs. There are quite a few people out there that do love the touch screen and keyboard combo, many of which will be well served by the Torch 9810 -- even if this is the device the BlackBerry Torch 9800 should have been.
