I've been interested in something like this for some time because most features of a smartphone ideally require a screen larger than is comfortable or practical as a phone. An inexpensive, discreet and small handset to make and receive calls, and maybe messaging but I'd hope that someone will make one that works on many devices. It's also great for device security.

This is where I think things are going. People will have one device for personal computing that can make and receive calls in standby mode using accessories such as this.

Yo dawg... I heard you like to talk on the phone, so we made a phone that talks to your phone so you can talk on the phone...

I would use the pygmy phone just for texting on T9, if HTC would allow it. Besides, I would love to hold a device next to my brain that isn't emitting microwaves and WiFi rays every second.

Reekly, wifi and microwaves use the same radiofrequency.

It's a no brainer. Especially for moving high powered microwave radiation away from said organ.

Good idea.

If I go mountainbiking, I'll still have two carry the giant phablet part with me, so this is essentially a bluetooth earpiece that cannot fit in my ear.
What would be totally useful is to have the carriers allow me to move my number between phones. That way, I can use my phablet monstrosity for everyday tasks, and my tiny and cheap bare bones phone when when do stuff that requires only emergency calling and compactness. Alas, that would be a pipe dream since the carriers will never allow it.

@sk8dad You can switch between cell phones by removing the SIM card from one phone and plugging it into another. I've done it with my iPhone 3s and my old LG phone, works. I'm on AT&T.

Agreed sk8dad. A phone is good for phoning and sms but screens are too small for internet and other functions. I much prefer Asus' other way of thinking with the padfone where you plug the phone into the tablet.
