Grant here:
Our experience has been the opposite of suphew's. Poor Dells and HPs but great Acer, Asus and Toshibas. No problems with any of them. A lot of bad experience with HP/Compaq. Haven't had a lot to do with IBM/Lenovo but what I have had to do with them made me decide not to deal with them.
With your budget you can get a very fancy machine. Do you want it for portability or just the fact it is in all the 1 unit? How about this that just came through yesterday?

For a TV tuner, due to the rapidly changing TV systems in this country, you need to be very careful what you get and it will depend on where you are. Any extra device like this will have to connect via USB.
You might want to consider a separate wireless keyboard and mouse and some good speakers for when you're using it at home.
As for anything else to get with it, it depends what you want it for. Are you going to use it on dial-up or broadband? If broadband, you might want to add a wireless acess point to your broadband modem so you can use the laptop anywhere in the house. The laptop has the wireless built-in.
If you don't need the portability go for a desktop machine as you finish up with a bigger, better screen, decent keyboard and mouse and the capability to add much better peripherals to add to it if you want as time goes on. Hunching over a laptop is damned uncomfortable for any period of time unless you put it on a stand and use the separate keyboard and mouse as suggested above.
The other thing you will definitely need is some sort decent printer, or maybe a multifunction unit.
