May I think out loud?
Imeo has already told us that the buyers of the Transformer have to pay an extra £5 to cover the cost of a locking button.
Would it not be fair, to those with older GG's to charge them that same £5 to have a lockable button fitted, even though this is a different button?
My line of thought is that the Trans owners will be paying £5 and those made from now on will have the new button, so that £5 would have to be charged to anyone wanting that button anyway..
Does that make any sense at all?
Hmmmmm.....
How 'bout I play Devils advocate here..... and say that if this was an issue of asthetics, I would agree with you, but because this is an issue of Safety, I think that the manufacturer should cover the cost of the switch, but the owner should cover the cost of shipping and handling.
Now I'll switch hats and say that Imeo could simply incorporate the 5 pounds into the shipping and handling cost, and everybody would go away happy!
Bottom line is that I feel the switches need to be changed. This IS a safety issue, and it's much cheaper in the long run to deal with changing a switch, rather than deal with potential problems dealing with loss of property and potentially, loss of life.
