Man, that thing looks to be perfectly the wrong size to be useful.  You really can't type with two hands on it, because it's too small.  You really can't thumb it, either, because it's too big.

Back when Ericsson did mobile phones (that is, before Sony Ericsson) they had a peripheral keyboard, the ericsson chatboard, which was smaller than that one, 49 keys.

That still looks like a lot of unnecessary motion. I like Palm and Blackberry-sized keyboards a lot better. They're compact and don't require a lot of movement to get from key to key.
 
The other thing I just thought of is that Ericsson accessory looks like it might damage the phone if you held it in the air while typing based on the weight of the phone on the connector.

They sort of designed the connector to handle large peripherals, though. But no, the chatboard didn't ever make it very big, I think that at the end they just handed them out at the stores and still noone wanted them.
