My son's 'Windows 7' package arrived today. He met the mailman on his way to the door.
Excited? You could say that. My son made a videotape of his opening of the package - complete with narration.
By now, 6:40 p.m., he's gotten it installed on his laptop - with only one glitch that I know of. A font he'd designed didn't get backed up. On the upside, he knows how he created it, and has some of the source files - but he'll have to re-build it if he wants to use it again.
Still, for an upgrade like that: he's had a very smooth time.
It helped that he's been doing backups and other prep for maybe a week now.
Did I mention that he's excited?
