HP Envy Touchsmart 4 Ultrabook 550 x 550The HP Envy TouchSmart 4 is an Ultrabook that is designed for Windows 8 and it has the touchscreen to prove it. It's not a hybrid Ultrabook though, which means you can't use it as a tablet instead of a notebook. The Envy has a traditional clamshell form factor with a touchscreen that's there to facilitate simple taps and Start screen navigation now and then, rather than prolonged use with your fingers.On the inside, the Envy Touchsmart 4 has a configuration that includes an Intel Core i5-3317U CPU, which runs at 1.7GHz and has two cores plus Hyper-Threading, and integrated Intel HD 4000 graphics. It's surrounded by 4GB of DDR3 SDRAM and a 500GB hard drive, along with a 32GB mSATA solid state drive. You also get Bluetooth, a webcam and single-band 802.11n Wi-Fi (via an Atheros QCA9565 module).
