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
