I went out and bought the 16GB black one on launch day. Aside from the OLED screen pretty much becoming a mirror in direct sunlight, and a very barebones browser, I am very happy with it.
They recently updated the firmware to 4.3 (191), which increased the overall UI speed, and made loading websites (especially flash heavy ones) much faster. Also, this firmware update increased compatibility and performance with 3D games.
This morning I downloaded PGR: Ferrari Edition and Vans SK8: Pool Service to my Zune, and the performance and graphics are spectacular. Just another reason I never got sucked into buying an iAnything.
Anyone else own one? If so, what are your thoughts on it?
