Sounds like you've got enough guts in your laptop to run Win2K but be warned:

Some laptops don't like running Win2K - It just won't install!

To be honest it's much better than Win98 but it will also be much slower loading up on boot! Is this an issue with your laptop?

I've personally got Win2K on all my computers (except servers and laptop) - I downgraded to Win98 on my laptop because it was faster loading and I only use the laptop occasionally at the weekends for short times so fast loading is quite important to me!

My advice ... try both ... there's no harm in trying it!
