OT: Laptop for Flash

Hi:

I’ll be traveling occasionally during 1 year or so and need a laptop to keep working in my projects. I’m not eager to spend a lot so, wondering if a machine like Compaq Presario CQ61-230SS will be decently enough or I should go for one with a graphic card with dedicated VRAM:

Intel® Pentium® T4200 2 GHz
4 GB DDR2 SDRAM
Intel Graphics Media Accelerator 4500MHD (Shared memory)
Windows Vista® Home Premium, Service Pack 1

I just do AS programming, animations included, almost nothing with Flash interface

Other software I run:
Dreamweaver
MySQL (XAMPP)

Computer at home:
iMac 20"
Intel Core 2 Duo 2.4 GHz
4 GB DDR2 SDRAM
ATI Radeon HD 260 Pro (256 MB)
Second monitor: LG M2794D

Thanks in advance
