NewInstance

I am planning to buy a new laptop for home work, hobby, and personal stuff. I am considering MacBook Pro, looks very nice and powerful: it comes with a "unix that works" out of the box, with hopefully not much hacking to be done to have full advantages of the whole hardware. The hardware is well known and I think it could also run Linux without too many troubles.
Now I am waiting for the new MacBook Pro to be delivered to the market, event that seems quite imminent, and I will consider buying the new models, or taking the old model with a good discount. Rationally I would prefer not to go for early stuff, and buy mature products, but this doesn't happen. Recently I bought this extremely bad and expensive product, but I am using it to read many books, so finally it hasn't been a complete bad buy.
I'm not sure I will use Mac OSX or Linux... Windows is out of discussion. I like Linux, but I never tried OSX, I want an OS that is primary good for Java development. Maybe I will go for a dual boot.
