The whole point of a laptop is to be portable and so having to carry an external keyboard and mouse with you becomes a bit of a hassle. That's why I always try and use the trackpad if possible whenever I'm in the mood to have a quick game. The trouble is playing first person shooters with a trackpad and built in keyboard really is a bit of a joke personally, unless you've got three hands or something! So for LAN sessions the trackpad's out of the question. But I can imagine other genres of games would be acceptable to play. So what do you lot do? Do you always keep a keyboard and mouse handy for your gaming needs or do you you like your portability and go for the compromise of using a trackpad?
