I also hate the touch pad so I bought a minature USB mouse for about $7.00, including tax. They are perfectly fine if your hand is small. I also carry two/three USB memory stick. And for the road, I also carry a 10' ethernet cable just in case. And don't forget to carry your charger/adapter.

My laptop is equipped with WiFi but if your's doesn't, its worth getting one.

In a pinch, I have a starbucks card, buy a drink and I have two hours free at starbucks. At Coffee Bean & Tea, its free.
