Wow, I wasn't aware of this....if more companies did something like this for the newer phones and they worked reasonably well I wouldn't be holding out on my Photon Q quite as long as I'm currently intending.  I wonder if the same company or another makes one of these for the latest LG phones?  If I were upgrading right now I think I might be drawn more to them than Samsung at the moment.

Someone, somewhere probably is making them for the more popular LG phones. I would imagine it would be based on the devices popularity. 

Is there quick response from typing to onscreen... and is the combo very bulky in your pants pocket?

Yes. Its is just as quick as it was with my G1. The downside to it is when the battery on the keyboard starts to drain you'll start to have a slower reaction and or will need to press the button twice. But with a good battery its pretty snappy. The battery easily lasts me all day, though if i were a heavy texter im not sure how long it would last. A full charge on the keyboard has lasted me up to 3 days...the bulk is there for sure and after a few months/weeks with the super slim S4 by itself you will notice the extra size. It's nothing crazy enough to make me stop using it. 

Gotta love the G1!

Yea, its been a long time...such a great piece of hardware

I carried around one of those mini bluetooth keyboards for a while using my original S2 and S3, but when i upgraded i found this S4 keyboard case and was pleasantly surprised by how well it works. I does get a bit janky when the battery is low but it works! Every year that passes though is another year i miss my G1 keyboard a little more...
