So what makes the Alto different from the rest of the notebook stands available? A quick glance will reveal most of the important details. The main one is the integrated keyboard. This is full keyboard, with number pad, built right into the Alto. (In fact the product appears in the keyboard section of Logitech's web site.) The next important thing to notice is the size- this is not a toy that slightly elevates the rear your notebook, it is a full-sized tool that is 19.1" deep when opened (9.3" deep closed). Other features include hotkeys and a USB 2.0 hub. The coolest details might just be that the fact that the unit can fold in half for traveling. It hard to call something this big "portable" but it can be moved from place to place easily and does not require external power, so it can be easily transported.
