As a follow up. I am running fully configured labs with all routers (IE
LABS) on an HP Laptop. Dual 2.5, 3G ram. Processor is about 30%. This is
on Ubuntu Linux with I HIGHLY recommend. Dynamips runs much smoother on
Linux.
I had never really used Linux until now. Ubuntu installed and recognized
all my laptops hardware, including the Bluetooth mouse and wireless
card. I got to say Linux/Ubuntu has come a long way. Couldn't be worse
than Vista.
Good luck

Hi:
How about Vista on a 2.2CoreDuo with 2GB Ram laptop?
Anyone have any kind of issues with Vista?
What should I watch out for?
Thanks !!
