Does anyone know when Leopard will become stock on all new Apple computer like Tiger is now? I really want a Mac for college with a budget around $2500 for a laptop which can get either one but I want to make SURE that they can run both Leopard and Windows Vista. I'm either going to get a Dell E1505 or a Apple but I really want a apple. So any info on when leopard becomes stock and if vista will be able to run on that would be great. Thanks.
