I've had BtStack Keyboard and Mouse apps installed on my iPad for some time now. With the 4.3.3 JB iOS, they were both unreliable - especially the mouse - dropping out frequently, loosing connection after turning off the screen for just a minute or so, and otherwise a PITA.
I am VERY HAPPY to report now (on my setup) that with the upgrade to 5.0.1 and re-JB, both KB and Mouse are quite functional and reliable. The mouse wakes the iPad (brings the screen back on) after it has been off for quite some time. (I need to perform some timed trials to know the extent of the connection persistance after the set hasn't been used.)
I decided to give it a try after remembering the mice up in the cupboard that I hadn't used for months. The mouse I have been using since yesterday is the Logitec V470 (I think that's the model number, but can't find an identifier on the mouse itsself). I also have an MS 5000 BT mouse, but haven't tried it yet.
The connection routine for both units is somewhat easier now, but still has to be performed using a specific order of steps. I know what they are and can deal with that.
I hope this will help some of those who would like to give the mouse a try. For some, who are trying to do more involved work that finger pointing makes somewhat inconvenient, the mouse is a real great tool.
