Designed by IBM in 1995, the ThinkPad701 became a top selling laptop, due primarily to the fact that the keyboard could fold out for easier use. Though very innovative, the need for a foldout keyboard was quickly diminished as screens got larger, allowing for bigger key layouts.

This is a concept computer called the Xentex Flip-Pad Voyager. The huge laptop comes with two 13.3 inch screens that can move independently of one another. Last time we heard (2008), this strange looking device was only available on eBay for a starting bid of $663.00.

As we're sure you read in our prior posts, the GScreen Spacebook is a laptop that offers dual 17-inch screens that can slide out for use. Sporting a magnesium alloy frame to cut weight, the Spacebook still weighs in at a whooping 10 lbs, and is slated for release this November. Should be interesting...

What you're looking at was part of the 'One Laptop Per Child' initiative that generated a lot of hype in 2007. These uber-affordable computers started around $200.00 and were built specifically for children. What you get for such little cash even now, is probably more than enough for a six year old, though we wonder now whether it'd be better off to purchase a tablet.

In September of 2008, Bentley (you know, the ballin-ass cars?) released a small batch of exclusive (250 units) hand made laptops, running Vista Ultimate, sporting a 160GB hard drive, wi-fi capabilities and a webcam, all neatly wrapped in stitched leather. Worth a totally affordable $20,000, it's a wonder why we never got one of these in the lab.

Late 2008, Lenovo announced the ThinkPad W700ds--an 11 pound beast with a 17-inch display that also featured a slide out 10.50-inch display, making it an ideal mobile work station for graphic designers and video editors.

This MSI dual screen notebook was unveiled at CES 2010, and features two 10-inch screens--the top screen serves as a standard laptop screen, while the bottom features a touch interface that allows you to do your computing via gestures and a virtual keyboard. Even cooler: this computer has been seen running a full fledged, Windows 7 OS.

We've seen and reviewed tablets that can dock to keystations (see: the Asus Transformer), but the Dell Duo actually allows the user to swivel the screen/tablet right inside the docking station, or you can remove the screen altogether for use as a tablet. This hybrid features a dual-core Atom processor and runs Windows 7 Premium.

The Iconia 6120 is the latest dual-screen laptop from Acer, and features some pretty impressive hardware specs: two 14-inch touch screens run with a Core i5 2.66Ghz processor with 4GB of RAM and a 640GB HDD.

This is the Waveface Light, a concept from Asus that features a flexible display that can be flattened for use as a tablet. The Waveface Light is part of a series of concept products including the Waveface Watchphone (which allows users to access important documents on their watch), and the Waveface Casa, a complete home entertainment center that can be used to watch movies and listen to music. All of these products feature unique, bendable shapes and functional qualities.

What started as a potentially awesome project unfortunately crashed and burned, though then again, Microsoft never did officially announce the Courier. Though no official reason was given to the reason why the tablet will never see the light of day, we're keeping our fingers crossed that a tablet that can be used like a book will hit the market any day now.
