I've switched from using the basic Putty to using a customized version called Putty Tray. Why? Because Putty Tray allows me to click on URLs! This is extremely useful while using naim, the console based Linux messaging client I use in conjunction with Bitlbee (I use Bitlbee to communicate on GoogleTalk through IRC).
Finally, no more selecting, clicking, and then pasting URLs into a new Firefox tab!
