If I were going to get an entire dedicated system for mobile gaming, I think a PS Vita or Nintendo 3DS XL would be a better choice -- they're both way cheaper, have dedicated controls for gaming, and have large libraries of purpose-built games. But I'm just not interested in more devices, especially ones I'd have to remember to charge and bring with me. I already have a smartphone, several desktops, two laptops, a Kindle, and an Android tablet. It's enough already.
