I'd found that one already. The search options are near worthless:

No resolution search.

A search for graphics chip manufacturer? Who gives a crap?

A search for manufacturer? If I knew that, I'd just go to their web site.

Processor type but no speed?

Weight and screen size are reasonable, other than the common problem of only being able to select one option at a time. (Looking for a screen under fifteen inches? That's six different searches.)

(Note that I'm not complaining that manufacturer and graphics chip searches are available, only that they should have been much lower priority than some other, more basic specs.)
