It literally took almost a decade of total and complete frustration of my time being wasted, but I've moved to the dark side. I now have about half of the 8 systems networked in my house Mac systems. Whatever version of Mac OS came with the $3k system I bought about 3 years ago just flat sucked as bad as Vista and Winders 7. Their new OS, along with my kids in college insisting on Mac machines (according to them, about 80% of IU students use Mac systems) finally convinced me to replace my desktop with an iMac.
Did you know that used computers aren't worth shit? I pulled a cat 5 cable out to my furthest barn and am just going to use my PC's in my barns for now. I've heard from several people that Microsoft's "Windows 8" is very similar to the new Mac OS. If that's the case, just hold out until Windows 8 comes out and you should have an easy to run system that you don't have to reboot constantly and that doesn't ever lock up. I'm still amazed that I'm yet to crash a Mac. Look at my olds posts from where I first tried a MacBook Pro. IMHO, it sucked! Clearly things changed quite a bit in a short period of time to make someone very cynical about Macs a convert.
The computer store that is still in operation on my side of town is the store I started when I was a "basement builder" and built up a good client base is telling everyone that they'll love Windows 8 because it's almost like a Mac. What really makes that odd is that they are NOT a Mac dealer; they have to send people to Best Lie to buy their Mac products but they do sell software for them and do warranty work on them. I think that part, Apple keeping a lot of control, is still a bit odd. Anyway, good luck. I'm sure you'll get it figured out. BTW, that 'all in 1' is the way to go, isn't it?! Man, I LOVE not having a huge CPU cabinet under my desk acting as a foot warmer anymore.
