C is out of the question.

I will say this: you'll have to decide whether you want to make the switch to a PC or not. As long as you don't drop them, laptops aren't as fragile as you think. And I have it on pretty good authority that if you wait until fall or so, the new version of Windows will be out and you won't be dealing with Vista.

Pro for iMac: you know Macs in and out, you're very comfortable with them.
Pro for PC laptop: portability. You'll be able to draw anywhere using it.

That's all I will say. Beyond this, I won't make a choice for you, just give you the better options.

Honestly, if I were you and in the position to make a purchase of this caliber, I'd go with a newer Mac Laptop.

But outside that, A. Because you're already familiar with Mac, and all the other bonuses that come with being on Mac OS.

A table Mac .... if only ...

I tend to avoid tablet computers like the plague. I see them frequently have issues with that little spindle that the display sits on, where the screen gets loose and starts falling over, or worst case, breaks totally off from the bottom of the laptop. I personally wouldn't buy one. But, I use my laptop a LOT, and laptops are something that I've been looking at for my business (photography), so for me, reliability is paramount.
A good warranty will cover most anything, but can't make up for days of lost work because your laptop was in the shop, or getting replaced. Given, you're not going to be using yours for work, so that may, or may not be as important to you. Myself personally, I'm likely to go with inexpensive PC laptops for us, with Linux installed on them when I get the money to do so. But once I start making enough off it to actually get NEW hardware, it'll likely be Mac laptops. The OS is MUCH more solid that Windows, I don't have to worry as much about a virus getting into my computer and trashing it, or my work. And right now, Mac OS, and Linux both have it over contemporary Windows systems for stability, and the ability to network with other computers and transfer large amounts of data (Like say a day or 3's worth of raw files) without losing any. Vista particularly has issues with this now and again when transferring files between it and another computer not running Vista. (And sometimes between it and other machines that ARE running Vista, though they have done a lot to make it better over the last couple years.)

You had the right idea in the first place going with Mac, I'd stick with it. The only thing keeping me from heading the same direction right now, is the price tag on a new Mac. But if you've got it, (And I'm guessing because you listed it as a choice you do), go for it.

i technically have the means to buy a cintiq wacom if i wanted to. But i'm not about to do that. An imac is enough computer for me at an awesome 24 inches. If I wanted (and I'm thinking) i could buy a dual wall monitor to drag reference photos to so i don't have to keep flipping windows on my screen.

Now that would be a really neat setup. :)

tablet pc with the accidental damage coverage? also back up your computer?

C, because of choices. You should also invest in a router (if you don't) that will knock down about 95-98% of illegible network traffic.

Custom built would be able to run your games if it is a Windows OS you choose. I dunno if WoW will run on a Macintosh tho.

There is a Mac version of World of Warcraft.

I wouldn't run WoW regardless. Warcraft 3, yes ... but WoW, no.

*nods* Also would be able to play many other games if you were so inclined. Stuff like Spore (which is very fun.) :)

I'm still waiting for Linux to catch up on this stuff. :)

spore was so cute :D loved it

Yeah, that's one of the things that kept drawing me to it. :)

I'll take note of that. *writes* "Xoa finds 'cute' to be selling point. Buy a puppy"

*snickers* You silly thing. :)
