After doing some research into new laptops, I think I will likely be waiting a few months. The main reason is that I want something that will be fully compatible with Windows Vista and will last me the next couple of years. The best suited would be the new Core Duo set of chips, but only a limited number of laptops have come out using it (with limited availability). Additionally, it looks like Intel is coming out with a low voltage version, which will probably be more suited to laptops.
So, in the interest of getting something that will suit me best and last the longest, I will probably be waiting a few months. If I get a tablet, it would likely be the Toshiba M400, IBM/Lenovo Thinkpad T60, or possibly a Dell Latitude if one comes out.
EDIT: I did manage to find this, which looks like a nice 1.83ghz Core Duo T60 with 14" screen. May prefer a 2ghz Core Duo 14" though.
