Some WLAN chips can create a lot of trouble, e.g. because the manufacturer doesn't want to release the hardware specs so that the kernel people (Linus Torvalds & his buddies of kernel hackers) could write proper drivers for those devices. I have read postings from other people that suggest that Acer TravelMate laptops use an unsupported (in Linux) WLAN chipset. It may depend on the model. I suggest you really really find out what WLAN chipset is in that laptop or you may get stuck with non-working WLAN.
Also: Sound is an issue on some laptops. If the sound chip is too new (no support yet in Linux) or if the specs are (still) unknown it could happen that sound doesn't properly work. I had that problem with my HP Pavilion dv2108EA laptop (solved now as newer Linux distros fully support the sound chip in that laptop).
It's hard to give any recommendations. From experience I know that the business models of most HP Laptops will work tip top with Linux (HP NC* and NX* series); most HP home models probably too (e.g. Pavilion dv2000, dv4000, dv6000 and dv9000 series).
Your best bet would be to make sure you have "Linux-friendly" hardware in your laptop as far as this is possible:
Laptop: Don't go for the brand-newest model; chances are it has hardware that isn't fully supported yet (your mileage may vary). Some brands are better in this regard than others.
Graphics: Go for Intel or NVidia, avoid ATI! (ATI's support for Linux sucks!)
WLAN: Go for Intel (e.g. Intel 3945abg) or Atheros (not too new though), avoid Broadcom BCM42xx chipsets (they can be made to work but it's a rather frustrating chore).
Ethernet: Some "Gigabit Ethernet" brands can make trouble; but usually standard Ethernet should work without bigger troubles.
DVD-Writers: LightScribe doesn't work as of now as it is a closed-source technology. Don't waste your money on "LightScribe" drives as you most likely won't be able to use that technology with Linux. Other than that DVD- and CD-writing should work as expected.

It has a nice database of laptops brands & models that are known to work with Linux.
