OK, this looks like the older one, with the "6" key on the left hand side.
If you use different keyboards--not just this one only--you may not like having to
adapt back and forth. I guess it's just personal--they had some good ideas with this
keyboard, but it's hard to get used to, i.e. it's hard to get a sense of the keyboard being "perpendicular" to your body when there's no "straight" lines anywhere on the keyboard....
hmmm.....guess I'm just picky....
