Any laptop computer with a wireless network card (and all newer laptops have them) will allow you to access email and newsgroups while you are on the road. Many hotels have free wireless internet, restaurants like Panera Bread or Starbucks have free wireless internet... and many more.
I don't know how you do your email and newsgroups now -- but if you use OE for your newsgroups -- you will probably have to use Google when you are away from home -- but you can still access them! As for email -- again -- OE probably won't work (mine doesn't on the road). But ours is through comcast ... and I can go to

anywhere inthe world... and get to my email.
So you can be connected pretty easily!
