Sorry, by "too big to carry around for most of the day", I basically meant in my pocket. My laptop is fine for carrying around if I know I will want my laptop, but my phone comes with me regardless. I can't imagine taking a laptop to a party or out to dinner, but I do this all the time with my phone. As such, I interact with it in a totally different way, and it allows me a huge amount of freedom. There are certainly a lot of computers out there that are no hassle to carry for most of the day, but it's still a conscious choice. It seems to me that the final barrier is the decision to carry it everywhere, not just anywhere.
