ASUS Eee Pad Transformer

Market Price: US$390 to US$469

With a price tag of US$390, the ASUS Eee Pad Transformer is an affordable tablet which comes with a nice 10.1-inch display, a speedy NVIDIA Tegra 2 dual-core processor and Android 3.1. The device boasts many powerful features, but the most fantastic part is that it's equipped with an optional keyboard dock which can not only turn it into a stunning laptop, but also functions as an extra battery to ensure usage of up to 16 hours. That's why it sold out on its very first day on sale. The Asus Eee Pad Slider, which touts its flexible slide-out keyboard, is also on the way.
