Sorry to prod at you again, but, HP fails in this regards too. Seen many a business grade HP chew through HDD's faster than necessary, suffer from crap batteries, and overheat while making a pile of fan noise just the same as my consumer grade ones. I do have an HP business class machine from 1998/1999, and if I could find a drive adapter for it, I'd still use it. When I finally retired it a couple summers ago it was -still- getting 1.5h from the original battery, and ran debian fantastically. Somewhere between then and now, HP screwed up bad. I will never buy another one of their laptops.
