in reply to Usage of tools
I've got pretty the same situation here, we got all workspaces packaged that they look all the same, have the same apps etc. But I can't work with a Windows-Computer that doesn't have BB4WIN, gvim, wincommander, putty and some other tools on it. People here tend to use gwedit for coding which I think is a not_so_bad_editor but well I'm so used to vi that I just don't want to switch to anything else. I would quit my job here if they would tell me that I have to use gwedit or ultraedit or any other weird editor :)
I think it's good to have all your stuff available on any computer, and that's what I've done. I put all the tools I use on my LAN-mapped-drive so that anywhere here I login I can start gvim with my settings, BB4WIN with my settings and putty (I created a batch that gets the stuff from registry and loads it back there...), etc.
And well if anyone has to use my computer it's not a problem at all, because he will see the same as he would on his own box, so I don't see a reason to change this. Everyone got his own tools etc he/she prefers so he should use what he likes to use and what is most efficient for them.
