I work as IT support. Last time before I bought an ipad, I had to carry around a notebook especially when I am on-call duty.
Today, with an ipad, I carry around in a slingback together with a bluetooth mouse. Whenever there's emergency at work, I use vpn to the office and establish a remote desktop connection to my PC at the office running Windows 7 and sometimes into the Windows Server.
Without btstack mouse, I find it very difficult to operate Windows.
The only valid reason for me to jailbreak my ipad because apple does not manufacture mouse for ipads. Now my bosses and my colleagues are considering buying an ipad and jailbreaking it, in order to use btstack mouse. It just work, if I have to do it again on future ipads, I will not hesitate to jailbreak it. I love using ipad with btstack mouse.
Ipad is lightweight and working with a bluetooth mouse, it is stylish.

Btw, it doesnt work with a bluetooth keyboard. But it is a far better trade-off using a bluetooth mouse with onscreen keyboard.
