I know the Compaq EVO N600c very well and have a couple of them. What i like is its design and looks + it can be used in an Armadastation EM that has 3 pci slots. I think the Geforce2 Go graphics in the Inspiron 8100 are better than the Radeon Mobilty in the N600c, but i have never used the EVOs for gaming, only work/office use. Sound is a PCI based ESS 1988 so native dos support are maybe not possible?

I can suggest another laptop, which has probably the best combination of DOS compatibility and processing speed.
It is Compaq Presario 1800. It has Pentium 3 up to 1GHz, ESS Solo-1 sound card (full DOS support, FM-music (OPL3 compatible), works under windows 3.1!), you can even use gameport if you have docking station, or solder cables to the mainboard if you can. It has also true 3D accelerator - Ati Rage Pro 128, with 8MB or 16MB of RAM if you are very lucky. You can play Quake games, Half-Life and similar stuff in full quality and good FPS. Even GTA3/Vice City should be playable with 16MB version; I have only 8MB, but i did some tweaking and i am able to launch it at 640x480.

To sum up, i think that Presario 1800 is one of the most versatile laptops. The speakers are also really great, they have some bass and give some surround feeling.

Here is video of DOS audio:

and here is GTA3 running (yeah, its not smooth but late 90s and 2000 games should be perfectly playable):

Great replies, guys! The N600c seems promising but i will have a look at the Presario 1800 as well. Thanks again.
