Shoot, nvidia's sandstorm was one of the better codecs out there, once upon a time. I haven't seen VIA's Envy series in quite a while, either. However, with HP's love affair with Beats Audio, we may see some better things out there. And to be honest, on my dv7, its pretty awesome.
16-55/28, 56/1.2, 18-135, 55-200
Minolta MC 50/1.4, MD 35-70/3.5, 300/4.5 and a bunch more.
