I've had the 8700 and now have both the 8100 and the 8800. They both have strengths and weaknesses. The suretype I have actually gotten to like and can type quite fast. I like the SMALL form factor of the 8100 while the build and feel quality of the 8800 is VERY nice. I like the keyboard on the 8700 better than the 8800. The spacing is better and the tactile feel was much better. The 8800 I find myself mis-typing a lot do to the cramped keyspacing (I have small fingers) and the overall feel of the keyboard is a little mushy for me. The screen on the 8800 is quite nice but the backlighting misbehaves in some situations. A software fix would be nice. Set to non-auto, it lights in darkness all the time (as it should) as opposed to sometime or never if set to auto. If set to auto, I find that in full sunlight it is viewable while in non-auto mode I have to hit the top button to force it to go to full brightness. Very irritating to have to toggle back and forth ... Those are the most glaring things I can say about the 3...
