I take it you mean layout in general, not just the key positions itself (which were quite good, not much else to say about that).

Here's some things I liked:
- multiple keyboard layouts despite of small production run
- LED backlight
- could be used left or right
- it looked a bit like the n900 keyboard, the best mobile keyboard I've owned.
- While not great in every aspect, magnets were a good way of working around a lot of problems.

About the only thing I didn't like about it was the amount of pressure required to press the keys.
