I recently made the switch from desktop to laptop and I love it. My desktop machine is hardly used anymore. Why would I want to sit in my cramped little office when I now have wireless internet and 6 hours of battery life

Seconded. Modern laptops make excellent desktop replacements; and if you intend to use it around the home, get a wireless network - it's one of those things you don't appreciate until you've used it.
