How does it compare to a good desktop keyboard? The only laptop keyboards I've tried are an eee 4G, an Acer 7520 and an Apple Aluminium Keyboard and none of them were particulaly good so I've no idea how much improvement a low profile keyboard can have.
It depends. I use a thinkpad as my primary computer, so naturally, I have to use the thinkpad keyboard
a lot when on the go/working in bed (there's NOTHING comparable to working in bed, really. If only the keyboard was better!). As far as notebook keyboards go, it's one of the better ones, if not the best. It's remarkably crisp and somewhat tactile, yet fairly light. Typing on it is definitely acceptable even if you're a BS user (you'll hopelessly bottom out, though, but there's not much else to do when using notebook keyboards). I don't know how the desktop keyboard compares, but the notebook keyboard is really good, at least as far as notebook keyboards go. In comparison with a BS board or Cherry MX, it just sucks.
What do you mean by tactile and more clicker? Harder to push down? Sharper drop-off? Easier to avoid bottoming out? Louder? Higher Pitched?
Clicky keyswitches should ideally have an infinitely steep drop-off. In reality, I think BS achieves this best--spring buckling is incredibly fast and in BS 'boards, the spring provides all tactility whatsoever, so when it buckles, there's nothing to hold the key up any longer; Cherry's MX and Alps with click leaves seem to have clickiness added as a bonus and not a design feature like BS, so I reckon their click is not as "ideal" as could be.
I've typed on some old white Alps (I think they're real, but I'm not quite sure--I don't know the keyboard model right now, but I remember it was made in 1990) and they feel just great. Not as great as BS, but still the next best thing I've ever typed on.
I'd be really interested in a Filco Zero if their XM switches are at least somewhat comparable; given me liking BS, I don't think I'd be too happy with a brown MX board.
