I don’t have a current picture right now but I recently or better finally 😉 switched from working on a 13“ Thinkpad to a 15“ Mac Book Pro. I loved the lightweight 13′ laptop and I carried it everywhere around with me. But it was really bad for my eyes I guess and not really comfortable working long hours so I’m really happy with my Mac Book now.
I always use a laptop stand (this one is called Griffin Elevator and I take the stand even with my while traveling), since I find it sooo much more comfortable for my neck. I use a wireless mouse and keyboard and my headset also has to be close by, since I need music to concentrate, especially if I work on theme code.
