We categorize first by state, next by office in that state, then by what type of machine, and then sequential numbering of those types of machines. So for the 2nd office in Texas we could have the following: TX02W001 - Workstation TX02V001 - Virtual Machine TX02FS01 - File Server TX02P001 - Network printer And then at the corporate level, we have the company name and shared resource type: ABCXS001 - ABC Company, eXchange server ABCDC001 - Domain Controller etc..

I've had a TI-89 since a freshman in college, had it thru my Batchelors and Masters in Structural engineering- and am using it every day at work.. the symbolic capabilities are very powerful. If you need anything more powerful than a TI-89, you have Maple, MATLAB and Mathematica. Besides, why do you really care about the graph on a calculator? You can't output it to WORD or EXCEL, you can't print it to your printer. If you need to document a graph, you either draw it by hand or use software designed for it- That's my take-
