Hey I am a web designer who travels to client locations to work with them on their sites. I am considering buying a Macbook Pro 13 inch (with 320 GB hard drive and 2.53 Ghz processor) and a 24 inch flat screen, or a 17inch Macbook Pro (500 gig hard drive and 2.8 Ghz processor). The first option is cheaper and more portable, but the second one offers bigger speed and faster processor. Any thoughts?

You've pretty much summed it all up yourself. Here's one thought for you though:
Although the 13" is more portable, the fact it has a smaller hard-drive means it will run out of space faster than the other model. You'll then need to buy an external drive for that one sooner - that detracts from the two benefits of getting it; it wont be as portable because of the external HD and it will cost more for the external.
