I have just ordered me a laptop with a shiny new yonah resting within. The laptops cpu was customisable on ordering, which leads me to strongly believe that it will be socketed, not soldered onto the mobo. So, if it is socketed, will it be interchangable with merom in the future? I know there will be a 667 and an 800fsb version, and the 800fsb is a no chance. It would be nice to have the option of a performance boost and 64bits in a year or so, once 64bit vista has taken off.
