Is foreign hardware different from american hardware or is the only real difference that the power supply is adapted to 220V instead of 110V and the keyboard layout is changed? When I was in france last time and I was working on a friend's computer and I went into the BIOS it went to US keyboard layout instead of the french one I was using. This was really annoying. Luckily I used to USA keyboard layout enough to guess my way out. This led me to beleive that the BIOS and software components are exactly the same and that the hardware should be the same too. I mainly want to know if I can buy hardware here and use it in computers in europe.
