The update is a little while away (Others more in the know may be able to specify) so I would just go with it. Either way, it's not gunna be a bad machine when the update comes out and will save yourself some cash in the process
Decisions decisions. buy it now and be happy, at least when the update happens you can be a hateful apple participant. but for now at least you will have a very capable machine. or you could buy an Eee PC? lol
