there really isnt any difference, except in price. .com and .nets are like 9 bucks/year, .info are like 16 bucks a year or maybe 8? i dunno, it doesn't make much sense to me.
I chose .com because i read many places that it is easier to remember a .com address than a .(anything else). Often times people will type in "something.com" when its really "something.net" but not so much the other way around.
I am trying to re-do so it is the way I got it from the factory and it says I am missing my Restore.log file. I have thought about pressing the f10 key while it is re-booting, and I was wondering if I should use my Recovery disks when it askes if I want to install a different opperating system.
