You may not need or want one. I think the bigger point is our ideas about portability are evolving. In the late 80s people who wanted a portable computer were happy with 10-15lbs machines that were basically portable desktops. Throughout the 90s we started to get something that looked like a modern laptop but still too heavy an expensive for most people to carry around. In the mid-00s we get the modern version of a laptop. ~5-8lbs, wireless connectivity, fairly inexpensive. In the last few years we're seeing the shift towards even smaller machines. Inexpensive <5lbs net books with wireless connectivity standard. So maybe the next step is <2lbs tablets. The trend of evolution is pretty clear: Smaller, more connected, lighter, cheaper, better battery life. For lots of people a MacBook Pro is no longer the ideal of portability. It's a heavy integrated desktop that has to be plugged in every 3 or 4 hours to keep working.
