For those of you who are worried about writing or accessing private material using a workstation or laptop supplied by your employer, the Palm TX might be a good solution.
I raise the issue because Amazon.com and Palm are offering a very low price on a Palm TX/portable wireless keyboard combo. With such a device you'd be able to slip out at lunch and check your email, favorite web sites, etc., from any place with open wi-fi access. Your nemeses in corporate IT would have no idea.
