Yeah, thread necromancy can be a bit annoying to read through and then one post throws you off and makes you check the date of the previous ones and go ***...that being said, there ARE some still valid points of discussion here and it's not just a random off topic flamefest.
I've used nothing but PCs since ohhhh about 3rd grade. Kind of got used to the "facts of life" with windows, IE constant upgrade patches, virus sweeps, etc. Most recently, had a custom built desktop (my 3rd windows computer) that caught a virus from of all things some military software (I'm in the Army) that I was trying to load onto it for working at home. Anyone familiar with the military, that software was PureEdge. Apparently, it had some sort of Trojan in it that slipped through both McAfee and Symantec (full corporate versions of both, downloaded off of AKO - Army Knowledge Online). This virus created a new "user" account every time I started up windows, resetting EVERYTHING. My settings, resolution, desktop, icons, etc. On top of that, I'm pretty sure it was spamming or something else because I had a 3.0ghz duo core, 4gb OCZ ram, 750gb HD, etc, etc, yet it was running slow. It overloaded symantec when I tried to quarentine/wipe the virus, where I had to cntrl+alt+delete shut down symantec, and did the same with mcafee. That was the worst one I've ever had, and got it from about the last place I expected to. It's what pushed me over the edge and made me think "let's go check out those new macbooks, because I'm really sick of this."
Walked into Best Buy first, looking at the macbook air, pro, etc. Mainly focusing on laptops because I'm about to deploy back to Iraq and can't exactly throw a desktop G5 into my rucksack. My other laptop is an Alienware, which ran well but very hot, prone to overheating in Iraq due to dust getting in through the multiple fan vents and everything in the case....but I digress. Anyway I really liked the look and feel of the MacBooks, except for the lack of things like a CD/DVD drive on the Air, which made me focus on Pros. I loved the touchpad having multiple finger swipe uses, as I have had an iPhone for a little over a year now as well. Made my way over to the apple store for some more apple-specific questions, found out about parrallels, and what programs mac has to rival everything basic in windows, and was sold. Bought a 15" MBP.
Since buying it, I've transferred 200gb of music over to iTunes from my desktop, all my old pictures, videos, etc. I no longer really play any PC games, so that wasn't much of an issue, and I've managed to find almost everything I need in Mac versions IE Office 2008, Photoshop, etc. No viruses so far, no freezing, no random slowdowns, battery life is awesome, it's LIGHT and PORTABLE like a laptop should be (compared to the alienware 15 pound brick I had before, with a power source bigger than the xbox 360's). Didn't have any problems whatsoever with my iPhone/iPod connecting and updating through iTunes, learned how to make ringtones through garageband (awesome!!!), it starts up fast and shuts down fast, no closing multiple "ninja" processes in the backround while waiting to shut down. Leave it on for days at a time downloading movies, and it doesn't burn my lap when I pick it up again heh. The built in webcam is awesome with Skype, quality of picture and smooth video is amazing compared to the $80 Logitech cam I used with my desktop before. I'd say the only thing I don't like so far is....um....uh....well, I was trying to find a Mac version of Steam so I could play Counterstrike once in a while, but apparently Steam is only for windows. Only other game I'm hoping they make for Mac is Starcraft 2...which they should since there was a Mac version of the original if I'm not mistaken. Got my PS3, Xbox 360, and Wii in the meantime.
To those who switched, those who are switchers, and those who will switch - *salutes*
***edit*** One gripe I have - where is the Mac version of Windowblinds for skinning the interface? I've found dock skins, widget skins, but no overall interface customizing programs.
