That's what I'm doing right now. But sometimes, I want to upload or encode a video and bring my MBP with me, I can't. I was thinking, let one machine do something, and another machine do something else. The base 13" MBP isn't that much of a downgrade in performance. The CPU is slightly slower in clock speed but is the same series as my 15". The graphics card is faster but it's not faster than my dedicated 9600M GT. The iPad is more of a toy than an actual computer. It's a tablet, but it's not a "computer".
