Starting with the Xperia E1, Sony considers it the "best smartphone in its class." It's a mid-tier device with a 4-inch WVGA (800x480) display, Qualcomm MSM8210 1.2GHz dual-core processor, 512MB of RAM, 4GB of internal storage, and 1700 mAh battery. There appears to be a rear-facing camera on the device, though Sony didn't provide any details.
Also included with the Xperia E1 are intuitive Walkman controls, such as shake-to-shuffle and a dedicated "long press to launch" button. Reiterating its focus on music, the Xperia E1 comes preloaded with a 30-day pass for Sony's Entertainment Network music streaming service.
If you prefer something a bit bigger and more powerful, the Xperia T2 Ultra and Xperia T2 Ultra Dual stroll into the smartphone scene with a 6-inch HD (720p) display, Qualcomm Snapdragon quad-core 1.4GHz processor, 1GB of RAM, 8GB of internal storage, microSD card slot, 13MP rear-facing camera, 1.1MP front-facing camera, and a 3000 mAh battery.
