The issues are minor. Apple does fix stuff. And with the retail stores, it's even better. I've been a PC guy forever, but I just switched to Mac. Got a 15.4" MacBook Pro.
Then my battery did the expanding thing. More than doubled in size. I took it back to the retail store (Yorkdale in Toronto), and got a whole new machine, no problem at all! Was back up and running in no time. If I had bought a Dell and something went wrong (and lets not kid ourselves, every company has issues occassionally), it would have taken ages to get the part fixed, including likely having to ship the machine somewhere and going without a computer for days.
Every manufacturer of anything, computers, cars, and even pens, occassionally makes defective stuff. What's important is how the treat you when it happens. I couldn't be happier than with the staff at the retail store.
Oh, and the computers aren't really that much more expensive. Considering you getting the top of the line chips etc, not old out of date Pentium M's or anything. Compareable hardware from Dell, Toshiba, etc has a compareable price.
First, PRK is available to civilians as well, most people just opt for the Lasik version because of the 'instant gratification' aspect. It takes longer to heal from PRK than Lasik. Ie, don't expect to drive for a week with PRK, while you can likely drive in 1-2 days with Lasik.
PRK and Lasik are very very similar, and both use the same lasers (thus have the same wavefront options available). The only difference is that with Lasik, a flap is cut from the top of the cornea to allow the laser to work on the middle of the cornea. With PRK, they wipe the epithelials (surface cells) from your eye (this is the 'grinding' process), and then laser the top of the cornea. People heal faster with Lasik because you don't have to wait for the epithelials to regrow. The regrowing (and smoothing) of the epithelials with PRK can take up to 4-6 months, though you hardly notice it.
After a while, the vision from Lasik and/or PRK is almost identical (with PRK often having a slight advantage).
PRK is also safer, since most complications come from the flap process. Ie, replacing the flap with a crease, bubble, or slight angle. Also, as stated in the summary, there's a chance of the flap becoming separated in the future.
For the record, I personally had PRK done just over 4 months ago, and recommend it to everyone. I was not able to have Lasik due to a thin cornea, but after doing all the research, I would have elected PRK anyway. You just have to suck it up for that first week, afterwhich you won't believe the difference. I now have better than 20-20 vision.
I also started with a TI-99/4A. Still have it. Started coding in the included BASIC and quickly needed to buy the Extended BASIC to access the voice synthesizer I got for free by purchasing 6 cartridges (and sending the tops to TI). Boy, those were fun days.

Next up, X-Ray vision!

You're on Slashdot, of course the relationship is the illusion.
