This is one concept phone I hope to see come to the consumer market.
It comes from a designer by the name of Antoine Berieux. The coolest thing about this concept is the fact that you can switch OS's by swapping cartridges, much like a rooted Android phone has can swap between ROMs. Each ROM contains a completely different OS, Android, or Windows Phone 7. Now, for people who like to try out different OSs or just like to have the ability to run each ROM this will definitely be a must-have if it ever makes its way to the market.
Another really cool thing about this concept is the fact that this guy created three different versions of the same concept; an Ultimate Edition, Smart Edition, and the Starter Edition. Each edition offers a different set of features and they are as listed below:
The specs for this concept are pretty nice, both the Smart and Ultimate Edition have great video recording to. The Smart Edition can and record in 720p and the Ultimate can record in a whopping 1080p. The Ultimate Edition also even comes packed with the 1.3 megapixel front-facing camera. Each edition's external memory is expandable up to 32 GB and has 1800 mAh batteries. This is a very nice and well thought out concept one that I think many of you would agree would be pretty awesome.
