Tablet computer 7

Convertible
Convertible notebooks have a base body with an attached keyboard. They more closely resemble modern laptops, and are usually heavier and larger than slates.

Typically, the base of a convertible attaches to the display at a single joint called a swivel hinge or rotating hinge. The joint allows the screen to rotate through 180° and fold down on top of the keyboard to provide a flat writing surface. This design, although the most common, creates a physical point of weakness on the notebook.

Some manufacturers have attempted to overcome these weak points. The Panasonic Toughbook 19, for example, is advertised as a more durable convertible notebook. One model by Acer (the TravelMate C210) has a sliding design in which the screen slides up from the slate-like position and locks into place to provide the laptop mode.

Sliding screens were presented at CES 2011. The first product to use it is the Samsung Sliding PC7 Series,a tablet with Intel Atom hardware and a unique sliding screen that allows the product to be used as a laptop or slate tablet when the screen is locked in place covering the whole keyboard. The concept still has to prove its reliability, but is intended to combine the virtues of tablet PCs with those of notebooks. Also presented was the upcoming Inspiron Duo from Dell, which rotates the screen horizontally when opened. Convertibles like that with hardware specs of netbook are called netvertibles.

Hybrid
Hybrids, a term coined by users of the HP/Compaq TC1000 and TC1100 series, share the features of the slate and convertible by using a detachable keyboard that operates in a similar fashion to a convertible when attached. Hybrids are not to be confused with slate models with detachable keyboards; detachable keyboards for pure slate models do not rotate to allow the tablet to rest on it like a convertible.
