There are two versions of the tablet PC -- the slate style and the convertible style.
Slate-style tablet appears similar to a large PDA. The approximate size of the device
is 8.5 inches by 12 inches, with a color screen measuring around 10 inches diagonally
with control buttons on the edge of the screen. The tablet PC connects to a docking
station and peripherals including keyboard and mouse, but can be carried around
as a mobile device, with a stylus for input. The slate design has the advantage
of being simple and sleek without hinges or moving parts, but it has no keyboard
or mouse when the device is mobile, away from the docking station.
The second style, the convertible, is essentially a laptop PC that converts to a
tablet PC. The convertible tablet PC has a clamshell design similar to the laptop
PC; but when opened, the screen side of the PC swivels 180 degrees, and the backside
of the screen folds down on top of the keyboard with the screen side facing up.
The size of the convertible design is similar to the slate, although slightly thicker
to accommodate for the hinged keyboard component. The main advantage of the convertible
style is its similarity to the laptop PC--a familiar device for the consumer. The
convertible style also has the advantage of the attached keyboard, but the hinged
clamshell design creates a bulkier device that may be susceptible to damage or breaking.
