I just got the AEBS today and after couple hours of usage, it is quite hot (temperature wise) so I am just wondering if it is safe to be ON all the time. Any users care to share their experiences please?
Mine was on continuously for about 18 months without any trouble. Recently went offline just because I upgraded to a Time Capsule. The AEBS was still working perfect when I took it offline. (In fact, I'm going to sell it on eBay.)
I've had mine on all the time for about two years now with no problems. As DjAmTraX said, just make sure you have adequate ventilation around the AEBS.
