I used a laptop, and yeah.. was more worried about heat than radiation. Most radiation comes out the back of computer equipment.. hence it's more unhealthy to sit behind someone elses monitor at work.. like workstations that face each other and you're behind their monitor.

I wouldn't worry too much Rae... altho I also wouldn't over do it. hehe. If I should have worried about anything, it's sitting in our office surrounded by loads of equipment... but Tallon turned out fine (so far anyway! LOL)
