If the Samsung SMX-C20 were an HD camcorder with the same comfortable design and features, I would love it, and would even expect to pay more than the C20’s $200 MSRP.
As it stands, I’d recommend spending more money and buying an HD camcorder before settling on the C20. SD camcorders are a dying breed and I suspect manufacturers will be phasing them out over the next few years. However, if $200 is your absolute limit, and you want more features than pocket HD camcorders typically offer, AND you watch all your videos online or on an old CRT television, then the SMX-C20 is worth considering.
Regardless, the C20 design is superb for casual shooting, and I hope to see more camcorders sporting the look.
