So it was mentioned in Bla1ze's review that the keyboard has been slightly changed in the 9810:
Physical Keyboard - Heading to one of BlackBerry smartphones best features -- the keyboard. We have some debate here when we compare the BlackBerry Torch 9810 to that of the BlackBerry Torch 9800. RIM says that the keyboard is minutely wider then that of the one found on the BlackBerry Torch 9800 and while I can't see or for that matter even feel the difference, I'm sure diehard Torch fans will notice it. To me though, it's the same keyboard. It has the same "clicky" keys that will eventually soften over time and become less noisy and is as responsive as anyone would expect a BlackBerry keyboard to be.
I was at BestBuy today and they had display models of both the 9810 and 9800 so I thought I would compare.
I don't know if it was because they were display models, but the keys on the 9810 definitely had more move in them... you could actually push the keys along the rows and if you pushed from both sides, they would bow a bit. (Not something I would try with my own phone but since it was a dummy...).
The keys on the 9800 were a lot more stiff and there was only minor give in them.
I tested this out on all three 9810 models (Telus, Rogers, Bell) and they were all the same. So, there is something different.
Again, not something I would try on my phone but something you can check out on a display model.
