New laptop will guild wars even run?

Hello,
Well needless to say after having my old family desktop for 7 years it has finally died. And since I will be attended college this year they have decided that it would be best to replace it with a new laptop for my birthday gift.
Now my question is will guild wars even run? I know laptops have come a long way since they were out (I've seen wow and such being played with no issues) but what con's will I be facing, as I'm not that computer savvy and I thought it would be better to ask here first.

Here's the summary:
Model: Dell, Inspiron 1420
Processor: Intel Core Duo T7100 (1.8GHz/800Mhz FSB/2MB cache)
Operating System: Genuine Windows Vista Business Edition
Video Card: 128MB Nvidia GeForce 8400M GS
Memory: 2GB Shared Dual channel DDR2 at 667MHz
Hard Drive: Speed: 120 GB SATA Hard Drive (7200RPM)
Optical Drive: CD / DVD writer (DVD+/-RW Drive)

Thanks for looking, Along with this one I'm looking at a couple of other ones also but i'm posting this one for now to see what I'm looking at gaming wise.

the 8400m should run it fine, my IG on my toshiba runs it fine.

Since you have 2 Gigs of RAM and a good processor, I would go with at least a 256MB GFX Card. But don't get a standard PC one (such as 7800GS) and stick it in your laptop, because they produce way too much heat for a laptop to handle.

There is no problem with this configuration, since Inspirons are designed as Workstaion/Gamer-notebooks which are quite powerfull. I own a Latitude D620 which has similar configuration except for the grafic card and GW is playable w/o problems.

Maybe the issue would be Vista, dont know if its possible to run GW on Vista ... maybe I am wrong ...

I run it fine on vista, some people don't.

I run Vista Buisness x86 (32bit) and I can run GW flawlessly
