Apple has launched today its upgraded MacBook Pro line of notebooks. One thing I noticed, besides the new i5 and i7 Intel CPU’s are the better battery performance of the new MacBook Pros (MBP). The new MBP now boasts of up to 10 hours between battery recharge for the 13-inch MacBook Pro and 8-9 hours for the 15-inch and 17-inch MBP. The previous MBP’s are rated only at 7 hours — which is already very good in my opinion. I’ve used other brands of notebooks and I can only get as much as 2 hours out of them.
