How are Bartons on laptops

[Byte]

I'm looking for a laptop but haven't heard too much about the Barton chips on them. How is the battery life?

i have a compaq presario 2100 series w/ a xp2400+ barton core, runs great and fast...id say my battery life is around 3 hrs...depending on what your doing of course.

They also have the barton 2600's out in their laptops. As for the 2800 IT is "out" but nobody has it in any of their configurations?
I really want a 2800 amd with a ati 9000 gfx chip. - it cannot be found.
