    I'm using a SSD in my Cortex PC (a laptop) as well as all my other PC's. I can't see any reason why you shouldn't use them. You have to be aware that SSD's tend to fail catastrophically- i.e. one...

    XP is now end of life, so if you are replacing your PC I would certainly upgrade. I would suggest Windows 7 is the safer choice, but know of no reason why Windows 8 shouldn't work. That said I'm...

    Yes, that's certainly possible. My point was, though, that I didn't want to get into these workarounds of the sort that you have to use if you are using X10 devices. For example, if your room has...
