The guy doing industrial design for the Gemini and Cosmo is the same one that did the original Psion keyboard. The key mechanism has apparently been improved, but I've not tried it. If the linux experience was better I'd probably have bought one by now.
If the extra function key row will fit without reducing the height of the main 5 rows then it's a good option. If you have to reduce the height of the main 5 rows the typing experience will suffer. The Libretto 70CT is a cautionary example here - its keyboard is ~2mm less than the Psion, but they squashed the rows to fit in a half-height row of function keys. It seems a tiny change, but even with my relatively small fingers it's a significantly worse typing experience. Key width is almost identical - the Libretto is a wider keyboard but has a laptop-style layout.
