"Specs include a quad-core ARM Cortex-A9 processor, 5-inch touchscreen OLED display with 960 x 544 resolution, dual analog sticks (not nubs as on the current generation), 3G, WiFi, GPS, a rear-mounted touchpad, the same accelerometer / gyroscope motion sensing as in the PlayStation Move, an electronic compass, and cameras on both the front and back"
For me it really depends on the price as sometimes Sony has a way of making things insanely expensive.
