Review: HTC One S for T-Mobile
With respect to music, the One S has an FM radio, the Google Music app, and Slacker Radio. The Google Play Store is on board if you want to purchase tracks directly from the handset, or download Amazon MP3, Pandora, or other streaming music apps.
On the video front, the S includes the stock YouTube app, HTC Watch, and a simple video player. HTC Watch is HTC's movie rental store. You can also download video content from the Google Play Store. The S also has T-Mobile's streaming TV product. There's some free content available, but you have to offer up a monthly tribute to T-Mobile's coffers if you want to access the best stuff (i.e., sports programming).
Thanks to the Beats Audio integration, music and video sound great through the S. I used several different sets of earbuds/headphones and was impressed with the quality. What I really like is that the Beats software has been buried deeper into the OS, and works with ALL media apps on the device.
The device also has a bunch of games preloaded, such as the popular Disney title "Where's My Water" and GameBase.
