I prefer wireless laptops. I can bring it over and show my wife or friends the web info I find instead of summon to come downstair to desktop PC. But I do use desktop for big downloads and few configs on router ect... Some graphic intensive game can't play well on my laptop so I use desktop as a last option. BUT for chat, emailing, search info on web ect. Laptop way to go. I can go Wardriving and find unsecured wireless to get online. Done this Done that. (I did use her neighbor's wireless access while I"m staying at my mother in law.) LOL.
I love freedom with laptop using webcam and chat friend on VP wirelessly so I can show him off something what I have LOL. Even show him something in garage or outside. (play stunts on lawn to entertain friends on VP ROFL)
But the drawback for laptop is that it's the BATTERY!! Mine don't last longer than 2 hrs cuz I have 6 cells pack. If I had a 12 cell pack, It would last me 4 to 5 hrs. So I still hooked to 120V outlet if not using battery.
