I've got the software on my "to do" list for checkin' out.
Granted, if you have 3GB of RAM, it's unlikely that one extra gig is going to be life changing, but it
is annoying not having access to a gig you paid for, just because the people in the industry
are were still are short sighted.
Who do you think you are? If you'd stopped winning, you could have been the Biggest Loser, if you gave up, you could have been a Survivor, if you'd stopped reading Orwell, you could have been on Big Brother!
