I want to replace my first-gen MBP, It has been a great laptop, the only problem was that I needed to change the battery three times in these years.
Now Im nervous about the built-In battery, how much will take them to change it?. I just hope they're not like those sonys.

You're completly right, im convinced they are equal, and thats something. I've been quite doubtful about getting a Mac because of some Windows apps I need but with these tests I make mind. I think my comment was biased by the Slashdot headline "AMBP Fastest Win XP?", and I lost focus on the positive results, and that it wasnt your claim anyway, just an observation you did. I think thats quite common in this forum, The headline being a manipulation. Sorry I fell for it.
