Summary: for logging in to *nix boxes, WebSSH wins.
Our sysadmin group was recently provided with some iPad Airs for emergency remote support when we're on call. We were also provied with the Belkin QODE Ultimate Keyboard Case. Their primary use is ssh access to various machines, and so I ook a look at the available free ssh clients to see if any were sufficient.
The first thing I came across is that the Belkin QODE case is not a good choice, because the Bluetooth keyboard includes no control key, and no escape key. Most of us are either vi or emacs users, and the shells like control keys, and various other utitlies rely heavily on control and escape so this was essential.
I already had an Adesso 3.0 Bluetooth keyboard that I use with my Galaxy S3 phone. It works fine (with ConnectBot, not available on iOS). It has both control and escape keys, and a more conventional keyboard layout.
It had a couple of other nice features, and I don't know if the others did or not because I didn't get that far. You could swipe up to see the scrollback in the terminal. And you could swipe the title bar left or right to get to multiple ssh connections.
It's still not quite perfect. The terminal size was off by one line. When I would start vi, there'd be an extra line at the top of the screen that was part of the scroll back history. Also, there was an odd mode where the bluetooth keyboard didn't work, but after fiddling a bit it came back. One of the other two had done this same thing. If I avoid hitting the keyboard icon it seems to avoid this issue.
WebSSH is the clear winner of the three apps I looked at (for our usage). There are other free SSH apps out there that I didn't get around to checking, because WebSSH is good enough for me right now. Some apps (in particular non-free apps) say they can remap other bluetooth keys to escape and control if your keyboard doesn't have them (e.g. use the "option" key as a control key). This might also be a workable solution, but I didn't get that far and don't really need to.
