funny thing everyone with a PC saying that mac's have less software. i have had a mac for the last 3 years and have no issues finding software for it. back in the day they had issues with software but now all mainstream software is made for both. we are a dual household, have pc's for the kids and getting ready to replace wifes 4yr old toshiba with a macbook. so i can speak both sides. while mac's might be more expensive up front there are a few advantages. about 6 months after getting my macbook the bezel around the screen started to separate a little. i took it to the local store and no hesitation they overnighted it to the repair facility and replaced the entire scree portion of the macbook. total time with out a laptop was 2 days. my wifes toshiba had HD issues a month after getting it, kept freezing up. well the only support they gave was over the phone and told me to restore from the HD. well i could not access the HD. my only solution was to buy a copy of win 7 and just start fresh. so yeah im a little biased on the Apple vs PC thing but the way they treat you i will never talk bad about them.
I've been using macs since the early 1990's. For imaging, video and surfing macs are great.
If you want to do any actual work (take a look at CAD/CAM and MRP software) you'll want to go with a PC. Corporate America doesn't run on a mac, it runs on PCs. That's just the way it is.
The mac fanbois will always tell you there's a work around to do whatever you need to do but like bubble-gum and bailing wire, you can only rig things so much before you start getting failures.
Not saying one way or another, just putting facts out there so the OP can make an informed decision.
