Man, I really can't decide.
Are black alps tactile and clicky or linear?
Oh and how do you set up a PS/2 keyboard for a laptop with a PS/2 USB adapter?
They are tactile but not clicky. I think the best way for you to tell is to get one and try it. They are not that expensive. For a while, you could get one for $10 on eBay, but I don't know if there are any for that price anymore. I got mine from Alan computech (or something like that) for $10 NIB. The keys felt much smoother when I had the legs raised. But since I used a keyboard tray this was not the most comfortable thing to do.
I used an adapter on the rare occasion that I used it on my MacBook. I tend to get USB keyboards because the Mac does not really like adapters a lot. I used it more at work where my PC had a PS/2 port.
All in all, the best way to know if to get one. What others, including myself, can give you is our personal experience and feeling, but we are not you and you are not us, and therefore it's hard to say whether you will like it or not. Just like dish, you can only tell if you'll like it or not after having tasted it. Looks and what others say about the dish can be deceiving.
