After seeing the HTC Tube concept, we had the real thing showcased, but not by HTC. ASUS PadFone is the very first tablet-phone hybrid and now there’s another prototype out there, dubbed TransPhone. This model is made by the China Union Branch, a firm made out of designers, engineers and phone manufacturers.

We’re dealing with a flat display panel, that can host an Android smartphone at the back. The phone part packs a dual core 1.2GHz Qualcomm processor, as for the tablet, it comes with HDMI and USB ports. We suppose there’s also a customized interface in the mix and you have to know that the slate prolongs the battery life of the phone.

No idea when this model will come out, but it’s in prototype/concept phase right now.

The Computer Systems Phone is a very interesting concept, that attempts to replace laptops by giving you all the features you need on a portable device in a package that reminds me of a PDA. The handset comes with an extra wide display and an embedded keypad, that can be pulled out from underneath the screen.

Computer Systems Phone works on Windows and shows us a curvy design, that many will love. This model was designed by Beau Reid, who also included a high megapixel camera at the back and many connectivity options. We have no idea on the exact specifications of this model, but it surely looks like something that HP, Palm or Research in Motion would make.

I guess that the model is running Windows 7 and it should pack a 5 inch display (just lucky guessing).

Knot is a multifunctional tablet for indoor use, allowing the user to browse the Internet, watch TV, listen to music and much more. The device is a mere concept right now, packing a 7 inch display, support for wireless hotpot and telephony functions, via a wireless attachment.

You can hook up Knot to a TV or projector, use it to access the Internet or rely on its USB and HDMI ports for connectivity. There’s also a front and back camera on board, plus 2W speaker and a 3.5mm audio jack. Capacitive buttons and a haptic feedback scroller take care of the navigation. Using this sexy sleek gadget to control your home seems like a pretty easy thing to do.

Let’s hope that the battery lasts enough, or we’ll just have to leave everything running and go look for a power source.

The raw idea behind this notebook concept is uniting two touchscreen slates with a hinge and calling them a laptop. The result is the Crowd notebook, designed by Philip Schaake, who is part of the German team Sensid Studio.

Brightly colored UI elements will allow you to interact with the device, reminding us a bit of Star Trek and Tron. The Crowd Notebook is able to separate into two modules, giving birth to two touch tablets in this way. This concept was a runner up in the Fujitsu Design Award 2011 competition.

I don’t know how this playful interface will appeal to serious users, but this would certainly make a great tool for DJs and people who have multimedia needs. Socializing and avatars are also the focus of this notebook, as are chatting, mail and web browsing.

Considering tablets are the most fashionable gadgets right now, one can forget that a couple of years ago MIDs were pretty cool, too. With a blast from the near past comes designer Choi Koun and the On Display MID, a dual display palmtop built around a dedicated Google search app.

If you close the device, the upper half shows a transparent display with real life feedback from social networking services. The MID is 20mm thick and it uses OLED technology for its screens. Considering the fact that we’re dealing with a transparent screen here, we can easily say that augmented reality would be nice to use on it, especially with a camera mounted at the back of said display.
