Microsoft Surface<br />

The Windows Surface tablet is one of <strong>the</strong> few<br />

tablets that support multi-touch. The<br />

mechanism that it uses is also slightly different.<br />

The screen produces a slight electro-magnetic<br />

field, which induces a current in <strong>the</strong> pen. The<br />

pen <strong>the</strong>n affects <strong>the</strong> EM field and <strong>the</strong><br />

information such as pen angle and position can<br />

<strong>the</strong>n be determined.<br />

Being one of <strong>the</strong> larger tablets in <strong>the</strong> market, <strong>the</strong> Microsoft Surface has<br />

processing power that can rival even laptops.
