OK, I can't resist. I have to chime in because honestly, I'm like the
Neuro (based on Neuro's stellar cranial reputation on this forum) of IT when it comes to this subject. Sorry, no offense
Neuro!! Between my knowledge and my associates' knowledge, I'm pretty solid on computer stuff ever since roughly 1985.
So now that I've established myself as an IT badass

, let me say this...
I could have written the posts by
Niterider and
intence01. They saved me a lot of effort. And they were mostly right. If you like iProducts, great. They are pretty, they do what they claim, they make a LOT of money for Apple. I agree with
Niterider, I also don't like Apple. I like their products for the most part but they are WAY too expensive. Apple is way too arrogant, greedy and controlling, not to mention hypocritical. That said, I've owned Apple before, an IT associate owns Apple currently and I may even own it again someday. But don't kid yourself. The hardware isn't any different. When you buy iProducts, you buy the whole rosy experience, the Apple ecosystem including the hype and the marketing. In reality, you have a different OS and slightly different software but with limited driver or troubleshooting support from Apple. Take away the matte Aluminum and the hardware is no different.
So forget brands and focus on what matters. Your data, your image files. What keeps them safe? What helps your workflow? Fault tolerance, backups and performance. Sorry but Win7Pro and a high end Intel computer + Lightroom + decent IPS monitor will get that for you. Spec out lots of RAM (16G +), and i5 or i7 CPU and a RAID1 Mirror drive array and you are ready to roll for at least another 3 years.
And FWIW, an iMac is a laptop with a 27" LCD attached. Fine if that's what you want but not worth over 2 grand. I've spent that but I have a i7 system wiith 32G of RAM, several 2TB Mirror arrays, 180G SSD, decent video and a solid 750W power supply/solid case. I also use a U2410 DELL IPS Display. It's been running for going on 2+ years. Runs like a champ.
What do I gain by spending more to have an Apple product? I don't fault anyone who does but I simply would rather put all that extra money toward a lens or even an iPad. (Even though I actually have a nook HD+.) I like Apple stuff just like the next guy but I cringe at how they take advantage of their customers' wallets with their overpriced products. They didn't end up having the highest stock price on their own! It required a high profit margin.
