Summary: Since new this TV has had problems maintaining a stable WiFi connection with my network. Obtaining software upgrades is difficult. Using Netflix or any other web application is hopeless. Tested many options. All other laptops, TV, and DVD players in home work fine with my current WiFi network. My final solution involved attaching a Samsung Blu-ray player to the Panasonic LCD TC-L47ET5 TV and using it to view Netflix and other web applications.
Summary: I picked this TV to replace an older Samsung LCD; my primary uses are games, sports, and the occasional movie. I used it for 2 weeks steadily. This TV was easy to set up - it found my Wi-Fi network quickly and offered a firmware update which installed without hassle. The remote is easy to use and the menus are responsive. The settings are, unfortunately, few, as it seems to lack advanced picture controls (white balance and the like).
