Windows 7 Tip: 
Lenovo has decided to unveil photos of its Pocket Yoga concept PC, an ultra-compact portable that’s slim enough to slide in a back pocket. The leather-bound device, which resembles an oversized wallet, features a QWERTY keyboard and a touch screen.
The Pocket Yoga appears to have adopted a similar design to that of Sony’s small VAIO P ultraportable computer. The VAIO P-like wide display has been combined with a leather-bound chassis to enable the sleek form factor of the system. This feature allows the end-user to carry the netbook in his pocket, making the Pocket Yoga an excellent computer companion, smaller than a netbook, but larger than your everyday smartphone.
Lenovo isn’t providing specs or other details at this time, and it’s unclear when or if the Pocket Yoga as seen in these photos will ever ship.
This is a great equipment, I would prefer to have this than an I-Phone.
