Macbook Air 13inch for Graphic / Web Design ?

Question

Hi guys, I decided to come here to ask for some expert help if i should buy the macbook air or pro. But before that, let me tell you what I usually do.
I use Adobe Fireworks as my primary design tool for web graphics / screen graphics, maybe use Photoshop / Illustrator for "brochure" or packaging projects in the future.
I like the fact that the 13inch air has a 1400 x 900 resolution, which is close to the resolution of my new monitor, around 1600 x 900 ( upgraded from an old aoc monitor that only displays 1024 x 768 )
I also like to surf a lot of videos, youtube etc, I dont play games that much since I already have an xbox for that. I don't do 3d or heavy video editing
In my old pc when I open like 10 browser windows, it slows down , and having a hard time when editing a project with 300 dpi on lets say a 20 x 20 inch canvas. My old pc still runs but a few times in a year, I get it repaired or I replace the memory ram or something.
This is my current computer setup which I bought last 2006 >
Windows XP SP 2
Pentium 4 2.66 ghz
1.5GHZ DDR SDR1 ram
nvidia geforce fx 5500 256mb
40gb harddisk
Based on what Ive mentioned.
1.) Comparing my old 2006 pc to the air, will it give me x 2 or x 3 speed on the things that I need ?
2.) Air doesn't have a LAN port, i connect my pc through LAN, but if I use wifi, will my net speed be slower ?
3.) There are rumors that there will be an air update this summer, to include the sandy bridge processors, should I wait for this ?
Thanks , hoping to hear your thoughts.

PC vs MBAir would be like comparing apples to windo.. err orange.
But regardless, there will be a very noticeable difference in speed when you upgrade your Pentium 4 to the MBA.
To put it in perspective, my MBAir 2010 seems to run faster than my Lenovo T410s core I5 CPU and both have SSDs and both have 4GB ram. Both models came out last year.
Wifi is usually slower than LAN. But I dont see any noticeable difference in speed using LAN vs wifi unless you transfer large files within your network. Your internet connection will usually be the bottleneck (when uploading/downloading files off of the internet) and is usually slower than your wifi (wireless G around 50ish Mbps vs 3Mbps DSL - with upload speeds being much slower).
I'd say if you need the upgrade, get it. If you'd rather wait, that's fine too - You'd just be stuck with your old equipment for several months waiting for the new model. (Or... you can wait until the new model is out, and buy the old model for MUCH cheaper price :D)
