I am using Core2Duo here and I am really at the moment concerned about the machines. Now the reason for concerned is that I am of the opinion that this technology Core2Duo is getting old and it will be better if I can just move out of this. I have given a thought for the MacBook Air and hence I am of the opinion that it will be superb if you all can put up light on this as well. I want to get cleared if Apple is going to make some more update on this MacBook as well. Please let me know if there is something new as; an update that will be available in the new MacBook. I really do not want to end up buying the older technology. So when are they going to come up with the latest one. Any help in the matter will be appreciated.
