I am about to purchase a Macbook Pro for the first time. I have been told the new Lion operating system comes out in Sept. I was wondering if I should wait to purchase the new computer with the new operating system or if I should go ahead and buy the new laptop and then purchase Lion when it comes out? I would like a new laptop as soon as possible but have no immediate problems with my current laptop other than it is a dell and has no battery life off the charger. Thanks for the help!
