I haven’t had much experience with the Eee PC like my coworkers have so I don’t know if the Eee PC gets uncomfortably hot after hours of use, but I can say that tonight I was using the CloudBook on my dining room table for about five hours and, after a while, I could feel a fair amount of heat radiating from the machine. I lifted the CloudBook off the table and felt the bottom. Wow, hot stuff! Perhaps this level of heat is to be expected for a device this small, but let’s just say I wouldn’t put this on my own laptop for long unless I was wearing a very thick pair of pants or wanted to avoid having children. I can’t think of an objective way to measure the temperature, but if any of you have suggestions, please comment.
