If you are in the market for new Ubuntu laptop check System 76's Lemur Ultra. System 76 is a Ubuntu-dedicated hardware company.
Lemur Ultra comes with Ubuntu 11.10 64 bit by default. So you don't have to do the (not too) hard work upgrading yourself.
You can see the hardware spec here detail.I'm bought (but I don't need new laptop right now) just by looking the Ubuntu key :)
