@Phoenix32890,
I use a small firm called machappy, a local place. Back in the northcoast, I used an official mac sales place in Arcata plaza. I might use the Apple store here, but it's way across town, and, besides, I like the small firm. Anyway, I've found both machappy and the mac store back in Arcata to be eminently trustworthy re leaving my computer. Both definitely helpful places.
On passwords, I routinely send my passwords to myself by email (one of the free ones), so I have a record if the worst happens and I have a hard drive crash with data loss.
So, if you keep a record of passwords, you can change them all just after picking your computer up if you are worried.
I've used pc's too, back in the eighties and some of the nineties, and, at work, in the 2000's.
My first mac was from the Bargain Box in the local paper - an old education system type mac. I got it only because I wanted a new computer, er, computer new to me, and that was the one that day in the newspaper. I remember being frightened that I would somehow ruin the machine by pushing the wrong button. I soon got over the illogical fears - even those oldie macs were intuitive.
I've never had a mac virus, knock on wood. I did get the hard drive replaced a while ago (babymac is now having a sixth birthday). The new hard drive is swell.
As long as I raved about my now local machappy place, and the mac place in Arcata, I'll have to add that there was a really good pc fix company up in Arcata too. Name was something like Renaissance Computing. Not that that is useful to a2kers, but just to record the good experiences.
