My usual workload consists of Mail, Safari, Adium, and Pages when I'm on the go, so I'm pretty impressed with the battery life. I do agree with you, the new revision is a good update but it's not something that any current MacBook or MacBook Pro owner should get worked up over. Remember, just because a new model is out doesn't mean your current computer is just going to stop working or it's going to look like trash -- it's a Mac, it's built to last, it'll serve you for a long time before you'd really need to jump to the next revision.
But hold on a sec, I thought that these new Penryn chip MBP's were supposed to provide a higher battery life? I've heard of many people getting over 4 hours on their current 15" MBP's - does that mean the same people should be expecting 4.5 - 5 hours on the new ones? (Cos that would be sweet!)

Doubt it. When running at full speed, the penryn probably has a noticeably better battery life (though remember that the screen, hard drive, graphic chip, etc. also take a lot of power, and improving the processor is just one component of power consumption), but when unplugged, most of the time in real use your machine is pretty much idle, and the processor speed already cuts back, reducing power consumption significantly.
According to this article from AppleInsider, we could be looking at an extra 18 mins for DVD playback, 23 mins for idle use (i.e. reading a document) and 55 mins for more processor intensive tasks.
