I have driven the new Nissan Altima, all of which have CVT and a Camry Hybrid. My impression was somewhat similar to what RichardL said -- that it seemed underpowered. It is a different experience from driving a traditional automatic transmission, and once you are used to it you may like it, but it felt odd to me. Always seemed like it was running at a lower RPM than I thought it should.
Something that I did find interesting is that the Altima still had the "AutoStick" feature. So basically, they have a couple of set ratios within the CVT that the autostick indexes to. I don't like the AutoStick in general, but to put it on a CVT to create "virtual gears" seemed laughable to me.
