[TenTec] (ham station computer choice)

[Bob McGraw - K4TAX]

I agree Jim.  As a beta test person in another commodity, yes it is those 
the grab it and run with it are in effect doing the beta testing for 
Microsoft.  In that case, I'll let them get most of the bugs out before I 
move on and thus enjoy the fruits of their efforts.

As to XP support, the fact that MS will no longer support the product as I 
understand will basically then no longer provide updates.  Now, if one 
should be using MS for security via the web, spam, and virus that could 
spell trouble.  However, I use a 3rd party paid subscription to handle those 
chores and thus I have little to no concerns in these areas.
