I have just got an e-mail from Greg Rosner - he is launching a discussion forum focusing on issues that people on the road may face, and how to overcome these.
www.roadwarriorguide.com is just starting, but it looks like a good idea. Greg contributes to Mobile PC Magazine as well.
Also on the site there is an eBook. The Road Warrior Survival Guide is available as a Adobe Acrobat pdf download. I will purchase that to read on my Pocket PC and check the tips and tricks - but will do this when Paypal comes back (it looks like it is just having some problems right now while I am writing this post).
