i checked into this very thing while shopping for laptops, as i'm usually near an outlet.

Yeah, any recent laptop should do this.
Theoretically speaking, Lithium Ion batteries don't get a memory so you don't need to charge the to 100% every time, and they don't like deep discharging, so once they get below 40% plug them in again.
However, you should use it the way that best suits you. Li-Ion batteries are a lot better than the older NiMH. They still wear out, but aren't as suceptible to abuse. So just don't stray too far from what your manual tells you and you'll be fine.
