I agree with Jeff, too often in the past I became reliant on something that was then taken away or was not available in a move/restructure. So I've come to rely on ctrl/printscreen for image capture, a word processor of any sort for image manipulation and documenatation and SSMS. And of course email to liase with clients and as a mechanism for getting sign off.

A working chair is nice but not important, the one I'm sitting on now slowly descends through the day so I "suck it up princess" and just keep re-adjusting.

Use what's available and make sure you can manage with the minimal.
