Verify your goggles has you focus on the horizon, and you'll enjoy them. > The first of many problems is that I have last built a desktop PC > around 2002 (been using laptops since) and thus have no hands-on > experience with modern gaming hardware.

Scenarios always come in sets of three: best case, worst case, and just in case. ------------------------------------------------------------------------------ Mobile security can be enabling, not merely restricting.
