I like being portable, and I just bought a brand new 17" MBP. While it is Portable, it's also large. I run a business, and would like to keep the power and size of the 17" but have something to travel with when I need to travel light. I'm thinking about selling my 24" iMac to partially fund a Macbook Pro 13" and 24" LED Cinema display. Dumb idea? Let me know what you think.
