My laptop is my primary workhorse, and I've just upgraded -- a very exciting time in any computer geek's life! On the left, my old 12" 1.0 Ghz G4 Powerbook, "zeppelin"; on the right, my new 13" 2.0 GHz Core Duo MacBook, "hendon". Zeppelin has been a rock-solid little machine for me these last couple of years, but it was starting to lose pace with my needs. Switching over to hendon been a very smooth process (other than getting Instiki to work again), and it's just so nice and fast -- it's better in every way (except for the size, I prefer the smaller formfactor). It should see me through me through the rest of the PhD in style.
