We all know by now (or at least should know) that NVIDIA is producing the graphics brain power behind the Zune HD and it's wonderful touch screen. Because it is being powered by the radically new NVIDIA Tegra ultra low power HD processor, the Zune is able to deliver on-the-go access to HD Video, Web Browser, Music and Photos with an exceptional battery life. With the capability to finally be able to view websites through a wifi connection on the Zune as well as a nice new touch screen, many people, my self included, are looking at this as a big contender for the Ipod. Microsoft has finally heard the voices of the people to include such software in the Zune OS.

The NVIDIA Tegra HD processor will allow you to be able to enjoy 720P HD content on your HDTV through the Zune HD, however, you will need to purchase the HDTV connector to be able to view the HD content on the HDTV. Are you sick of hearing HD yet?! Good cause I got more. The Zune also down-scales the video on the player it's self to fit a resolution of 480x272 which is not HD...obviously. This is just for the Zune screen and not the HDTV connection which, again, gives you the 720P HD quality.

The wifi connection is a great addition to any MP3 player as you don't need to have a wireless plan through your favorite cell provider. I'm sure they would be more than happy to have an opportunity to charge for that supposed "fast" 3G service. I have that service on my cell phone and while it's ok, it's not incredibly fast. Then again, I don't really use it that often to see it's true potential so I can't give realistic feedback on the 3G network at this point in time. The wifi connection, however, is 802.11b/g compatible and supports authentication modes: Open, WEP, WPA, and WPA2 Encryption modes: WEP 64- and 128-bit, TKIP, and AES.

Moving on to the touch screen, it is very unique and with a 3.3 inch screen it provides a 16:9 aspect ratio with a resolution of 480x272 and a Scratch-resistant glass with Touch input capability orientation: Vertical (music) and horizontal (pictures and videos). This is unique in the fact that it uses the newest technology called OLED. OLED's are made from organic (carbon based) materials that emit light when electricity is run through them. Because OLED's do not require a filter to change colors (unlike LCD displays), they are more efficient, simpler to make, and much thinner. OLED's have a great picture quality - brilliant colors, fast response rate and a wide viewing angle. The materials for OLED's were discovered back in 1960, but only in the past 20 years or so have researchers started to actually work on the technology.
