For me, the angle matters, but also the softness of the touch. For this reason I have loved the Kinesis Freestyle 2. I really tried hard for some weeks, and much customization, to like the Kinesis Advantage, which is programmable, but the keys were just too stiff for my hands' comfort. Maybe someday I'll have to try more of the other kinds, that people discuss. Time/$/priorities... Edit: I've tried multiple MS split…
If you are willing to part with the keyboard I would buy it from you. My Microsoft 4000 keyboard finally stopped working and I’m looking for replacement.
I should probably reset the key mappings to factory default before sending it to you, unless you want to try my layout for some reason (I can send you rough notes). I didn't like theirs (made my thumbs push sideways too much). But the user manual says how to reset it.
I hope the inner box is good enough for shipping -- cardboard, not especially thin, but originally it had a bigger shipping box around it. I'm thinking, I add tape, shipping label, put outside on the right day. We can also drop it at the post office or FedEx office, but you might have to wait longer that way, until we happen to be near there (edit: health slows me down currently).
If you still prefer to pay, you can do it by reviewing my web site and providing suggestions (but not required). I don't plan to add pictures or visual design, but I do plan to consider a sans serif font later, and I hope it can be useful for some people, for some things, so suggestions welcome. Especially when considering the first link "how to read content at this site...". Another payment is if the keyboard is useful to you, after some months, I'd be glad to hear it. Or persuade DanG (dang) here to un-shadow-ban any comments that include a direct link to my site. I'll try not to post so many as when he did (oops -- I thought at the time they could be useful, but probably overdone); I think he does a good job really for the site.
