I recieved my Vaja case, and I have to tell you I am impressed. This is my 10th Vaja case to date and the nicest one I have seen. It makes the 7100 feel MUCH more solid in my larger hands and makes me a lot more comfortable typing.
Earpiece volume was not effected at al (something I was concerned about). Ring volume was not effected either, but I have been using a full leather holster that covers the speaker anyway (the one from ebay).
Here are some pics:
This is a comparison of the 7100t with and without the Vaja Case. It's definetly larger, but not so much that it's rediculous (like a Treo)- just enough to make it solid.
Here are a few with the Vaja in my hand:
And here is an upclose to show you the case quality and fit:
Obviously the case doesn't support the sleep function, but I cannot comment quite yet on how the will effect batter life. I often carry it in my suit pocket though and am use to turning it off manually and locking the keyboard.
All the buttons and the sync cable port is exposes and easily accessible.
Personally I am very impressed, but will post back after I have ised it for a few days.
I also bought the new Pro Clip connector that supports this type of case and will let you know how that goes after some use.
