Thanks for your reply,

Ok, thats new to me. But my time machine copy is based on Snow Leopard, what will happen if i copy the time machine copy to the new Lion macbook? I remember using time machine on my old mac, because i had to send it to a mac store for a repair. When i got it back it had a clean instal of SL osX. I used time machine to place everthing i had back on the Macbook, cant recall any problems but that was more then a year ago.. And it was all on the same machine, i dont know if that matters?
