Ubuntu and HP Pavillion laptop dv2000

Hello, I have an HP Pavillion dv2000 laptop that's about 1 year old. The
hardware is exactly as it came from HP. The preinstalled Win Vista on the
laptop got broken and I want to try something new. I am fairly computer
knowledgable. I have made many home-built PCs, however this is the first
laptop I ever owned and I've never seriously used Linux. Now I am thinking
I will try Ubuntu on this laptop. I've heard that driver support for some
Linux distros lags way behind. Do you suppose I will have driver issues
between Ubuntu and this HP Pavillion 2000 ? I do want to use the wireless
internet and the sound hardware. I don't mind spending a little time
searching for drivers. But what if drivers aren't available or they have a
lot of bugs?

Does anybody here use Ubuntu on a HP Pavillion?
I hope someone here will give me some advice about this.

TIA. Bill S.
