OpenSolaris on Laptops?

Up until recently I have heavily relied on my old and trusty Apple ibook laptop. Unfortunately it finally bit the dust a couple months ago (I think the system board is fried). My ultimate plan is to replace the ibook with a shiny new powerbook, but my budget will not permit the purchase of a new powerbook in the next few months. I've been thinking about getting a Dell laptop to tide me over until then, so I at least have something I can take to Starbucks and work from.
