Maybe from a hardware perspective, but not from a usability perspective. No right control key. No page up or page down. No home or end. No delete key. No number keypad. I was in love with the ergonomics of it...for about a day.

Home and end are function-left/function-right, Page up/down are function up/down, and what you're calling "delete" (Apple calls it forward delete) is function-delete. This is how the whole line of Apple portables are...

Not sure how those work if you're not using a Mac. Maybe you can remap the right Option to Control? Control isn't near as important for most Mac users since Macs use Command where windows uses Control.

I'm using it for both. I find it tolerable under OSX (precisely because of the Command key thing), though I don't like chording for things when there's a perfectly good one key option (like delete, home and end). And how do you Shift+Home/End for selecting? I forget, I know it's possible, but it's also a pain. I finally just punted and bought a Logitech Wave for it. I like it much better.

You have a curious definition of keyboard usability. I was unaware key presence was keyboard usability.

Perhaps you're right. I guess it's more of a keyboard efficiency thing. I can still DO everything I can on a full keyboard, just much less efficiently.

Well, I don't think that's what a portable lightweight bluetooth keyboard is for. It's very comfortable to type on, is fairly durable, and is quite light and reasonably small. It's not meant to replace a full keyboard, just to be a decent substitute.

That said, once I did the ctrl/caps remapping I've used that keyboard extensively with emacs and only occasionally did I feel any real limitations.

Except it's what came with my full-size 27'' beast of an iMac. That sort of thing should come with a full keyboard or something that's supposed to be a substitute for it. If I'd gotten it with a laptop purchase, then yeah, I wouldn't be complaining. It would be pretty cool for that. It works fine with Vim, but not XCode or Visual Studio, which are my two primary uses for the iMac purchase.

They let you choose which of several keyboard-mouse combos you want with your computer, all for the same price.

Not at Best Buy, apparently. I probably still would have chosen the smaller one and then lived to regret it, though.

My physical therapist actually made me switch to the smaller wireless keyboard, and the lingering remnants of my RSD went away. Just shortening the distance between keyboard and mouse made a huge difference.
