So, these long lasting batteries for the new MBPs are making me jealous. I have one of the "Collectors Item" MBs. I haven't been thrilled with the battery life (who really gets 5 hours?) I'm wondering about what options there will be in the next few years in terms of replacing the battery. I know that I can't replace it with one of the non-user replaceable ones or anything like that. But I am wondering if there are options out there, that have better life than the one I got with the computer. Are there going to be more efficient batteries that will fit in my MB or has the technology just moved on to whatever this new type of battery is? Obviously, I don't know anything about batteries. Thank you.
