I started working with Apple products on the Apple 2C! Since then, I've been a PC man, but I've always built my own (except laptops). My first experience with Apple (other than the iPhone - I had the original iPhone 3G which sent me running to Android. I'm now back on the iPhone 4s - much improved) was when I bought an old Mac Mini for my kid to play on. It was $100 used online and I dropped the cold hard cash. It worked for 3 weeks then went belly up. I took it to the Apple store and they were very helpful. They gave me new system discs and applications discs for it without question.
While I was waiting for them to burn them for me, I checked out their laptops. One thing that has always driven me nuts about PCs have been their laptops. There seem to be no standards in quality or system loads and you never really know what you're getting. I was pleased with the MacBook Pro that I played with. When I went to a buddy's house, he had an MBP that he had used for 3 years. I tried it and to my surprise, it worked just about as well as the one in the store. My HP 64 bit, 8GB RAM uber-laptop went about 6 months of heavy use before it started dragging and skipping. (Bear in mind, NONE of my own computers that I've ever built have ever done this! In fact, I just pulled one of my servers out of commission after nearly 12 years of running. It was an AMD 350MHz running Win 2K AS and it never got rebooted unless the power went out for too long or I had to load patches. I used it all the time and it never went slow!)
Since I got my MBP, I've begun drinking certain formulas of the Mac Kool-Aid. I got my wife a MB Air and I got a big, fully-loaded iMac for video and composition work. I also have the iPhone 4s and the iPad (and just got my wife the iPad 2 for XMas). So, yeah, I've been drinking it. However, there are a few bits of "fan-boy" lore that I don't subscribe to. The fact is, the PC is just as viable of a platform as the Mac. I still use my Dell laptop for remote recording (Credit to the Dell - the series of laptop that I bought had absolutely NOTHING on it except Win XP Pro. NO bloatware of any kind). I also still use my power house (octa-core 32 GB of RAM) PC that I built for in-house editing and mastering.
Yeah - I love my Macs. However, one platform isn't inherently better than the other. To me, the biggest benefit of the Mac is the consistency between platforms. If Windows could manage that, they'd be the only game in town. However, since most Windows machines are made MUCH cheaper by software subsidies (in other words - crapware vendors pay them to load software on the computer thus driving down the costs), it's a trade-off.
A good solution for PC users looking to use their machines for audio recording - do a good ol' fashioned wipe on the stock drive and load in a fresh OS (spend the $$ and buy a new copy - it's only $100) with no crapware. Then you'll have a Windows machine running just as well as Microsoft intended.
