Was the Kensington 120W power supply entirely replaced by the new one with USB tips? In June I had no problem finding a replacement tip for my Motorola phone at Circuit City, but I've searched everywhere (retail stores) for a 'G' tip and have seen no trace of the old non-USB style.

I have quite the investment in the old style of tips and am not keen on having to replace them all. Would it be worth finding an extra power supply to have as a backup down the road (I'm already on my second, after shorting the first due to bad tip designs and the Y-splitter).
