Kanvus Light 64
One thing that you can't do with a PC that you can do with a tablet or a simple piece of paper is doodle. Until recently, you needed very high-end graphic designer systems to interact with your PC screen like you would a piece of paper or a canvas.
While tablet computers and, of course, the iPad, let you use your fingers or stylus to navigate through your menus and applications, a series of pens and slates from Kanvus now brings the same capability to standard PCs.
The Kanvus Light 64 is a soft, light and compact 15.2cm x 10.2 cm slate that acts more or less like a mouse pad. But instead of using a mouse to move the cursor on the screen, the system gives you a pen, so it feels like you are writing on an actual piece of paper.
There are plenty of things you can do with the set-up, such as drawing or scribbling just as you would on paper. You can also use the system as a way to write messages or even e-mail. It also works with basic Office applications so you can put notes on top of documents or presentations.
The slate is described as an electromagnetic digitizer and plugs into your PC via a USB port. The Kanvus Light 64 gives you an accuracy of 2048 lines per inch. The pen itself runs on an AAA battery. The Kanvus Light 64 costs HK$399.
Pros: lets you interact with your PC like you would a piece of paper
Cons: relatively small writing and drawing surface (Kanvus also makes bigger models)
