    Charge 10 iPads at once?

    Hi all. I know the iPads only draw about 10watts but I am having a hard time finding some kind of power strip that will charge 10 iPads at once. I could just plug all 10 iPads into plain old power strips plugged into a few outlets but that would be a bit cumbersome. I was looking at items...

    G5 Quad Gluttony!

    So after 2/3 years of putting up with an unsightly '12' in my system profiler under memory, I finally got some cheap DDR2 DIMMs to bring me on up to 16GB. For some reason when I first put them in it only detected 2 of 4. So swapping 4 x 1GB for 2 x 2GB was naturally not much of an upgrade. I...
