The Sony NWZ A820 series is Sony's latest addition to their Walkman range of DAPs. It comes in capacities of 8 and 16 GB and its USP is the inclusion of Bluetooth to please all those cable-haters among us. For those people who don't care about Bluetooth [like me] Sony has also launched the NWZ A720 range, which is exactly the same as the NWZ-A820 with the exclusion of Bluetooth. The NWZ A720 series sells at the exact same prices as the iPod Nano, with the 8GB selling for 199$ and the 16GB for 299$. The Bluetooth enabled A820 comes for 269$ for the 8GB and 319$ for the 16GB. In my opinion, this is it. The iPod/Zen/Clix/D2 killer we all have been waiting for. Why? First off, and most importantly, it comes with Sony's legendary Audio quality. Any audiophile will tell you that the entire Sony line-up leaves the iPod Nano in the dust when it comes to Sound Quality. The inclusion of the in-the-ear MDR-EX082 earbud makes it even better. The screen is 0.4" larger than the Nano, and makes viewing videos a lot sweeter. It also has an insane battery life of 35+ hours for Audio and 10 hours for Video. And if you don't need stereo Bluetooth [which I don't recommend, as it does drain battery life pretty fast], you get it all at the same price as the Nano. And no, it does not need Sony's evil software, SonicStage. It works perfectly well with WMP11, which I feel is one of the best options out there to keep your device synced. I'l actually be heading up north for a vacation and if I see the 8GB A720 in Delhi for a reasonable price, I'll sell my Zen without a second thought and buy it.
