So sure, the iXoft might look like a small quilt or over sized pot-holder to throw on your lap so you can use your notebook in comfort, but a quilt's just going to make your notebook run hotter. At $25 to $30 retail, the iXoft Notebook Cooler from Thermaltake isn't cheap. But it keeps your lap comfortable and your laptop cool.
The Micro Temp MTPRO is a fun tool. Essentially point it at something you want to know the temperature of and it will tell you. Take one of these bad boys to a party and things will really get interesting. People will start taking the temperature of their drinks, the wall, the light bulbs.. even each others heads.
