My PS3 gripes:
How can I tell when my controller is fully charged? When you have it plugged in, the controller number light is solid
Is there any way to charge the controller while the PS3 is not on? I'm guessing you can charge it from a PC, but I haven't tried it. No, I'm not buying a special charging station. You can charge it with a PC or laptop USB port. Between recharges, I get about 15 hours of gameplay.
Also, why is the cord so short? I don't know but Sony wanted to make sure people could recharge out of the box so that was probably the cheapest way.
What happens if I'm running low on batter and want to keep playing? Do I have to sit 3' from the TV?The solution is to buy a longer cable. A decent length can be found for less than $10 and some people probably have a couple longer spare ones lieing around from their PSP, computer or digital camera.
