Nobody has a 100 GB 7200 RPM for laptops yet. My guess is that Apple will be among the first to offer this when it happens though. This is probably why Apple hasn't offered 7200 RPM HDs in their lineup yet - mst consumers would want to pay extra to do a BTO option that gives them less space than a 5200 RPM drive. Personally I use a fast externmal drive quite a bit. I may up the internal to a 7200 RPM drive when Tiger comes out though.
