I am a long time Mac user, but I've spent enough time on PCs to know that you can do anything on a PC that you can do on a Mac... some processes are more efficient on a Mac some on a PC... to reap the benefits of such efficiencies you have to really know your computer well. So, if you know PCs better as it sounds like you do, then why not stick with it unless you really are lusting after a beeeutiful new powerbook (they are mighty pretty). You will most likely have to buy at least some new software licenses as others have pointed out, if you go Mac. Plus there will be a bit of a learning curve, although it's nothing even my mom can't handle.

I'd like to argure that there is not only one way to do things on a mac, maybe for the unfamiliar it would appear that way, but you can geek out until your eyes bleed with macs. Their Unix based OS is very very flexible, if that's your kinda thing. If you like Dos, stick to PCs.

I'll also add that even though nobody stated otherwise, yes Macs do break down. My Powerbook just got out of the shop... I used it so much over the past 2 years that I killed the 60GB HD. Luckily I cloned it recently (very easy to do BTW). I bought an Apple Care package with my PBook and they just replaced the hard drive ($100+) and upgraded my OS ($100+ value) in less than 2 working days. Plus they are great on the phone helping me out with stuff, although their hours could be better (not 24 hrs). Oh yeah, this cost me NOTHING... Whether you get a PC or a Mac, if you get a laptop I recommend a good warranty!
