One more thought: if a battery has to be changed very infrequently, the annoyance experienced at that time is considerably greater than when the whole process is routine. Watch batteries also have the added inconvenience that it's often difficult to replace them, you risk damaging your watch, and you often have to go to a specialized store to even find that battery. I think a closer everyday item to use for comparison would be a wireless mouse. As far as their power supply is concerned, mice come in three kinds: - wired, power comes over the cable, - rechargeable battery, usually not replaceable, - one or two AA maybe AAA cells. The rechargeable ones seem very nice, but once the battery dies, you have little choice but to throw it away, even if the rest of the mouse is still in good condition. The ones with AA cells used to run for a couple of months on a cell, but modern ones should last a little longer. Having the mouse run out of battery is of course annoying the first few times, because Murphy will have made sure that you used all your spare batteries at the time, or just can't find them, and it's the night before a major public holiday with absolutely everything closed. But after a few replacements, you'll learn to prepare. So you just keep a pack of batteries at the desk, only for the mouse. The whole thing becomes routine, especially because it happens relatively often. Unlike a most wireless mice, Anelok also has the option of going to USB power if all else fails. - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
