I currently have 3 batteries on my macbook pro (17 inch). It's nice to be able to go unplugged for 8 hours, but keeping them all charged and swapping them around is a pain in the ass. I'd personally trade multiple swappable batteries for a nice integrated solution. Especially if it lasted twice as long, and had 3x the lifespan. And if it goes bad after 3-5 years, $179 for a battery replacement doesn't seem like a huge deal to me. So, yeah, count me in.
