I've found a local offer of these - never used keyboards in boxes, incl. wrist pads. Made in China 2005/03. Does anybody know if they are good or bad keyboards?
I used a 1996 rubber dome IBM KB-8923 before. It was really smooth for typing (possible the best rubber dome I've ever used) but extremely loud (clacky) at the same time.
Does anybody know, how do these IBM Preferred Pro Fullsize compare to that 9 years older model? Thanks!

I've always really liked the preferred pro boards from IBM & Lenovo, they get mistaken as 'mushy' boards when in fact they are just really smooth.
I don't know how they compare to older IBM rubber dome boards though.

Thanks! It's already on its way. I'll share my experience when it arrives.

Is that a thing? Mistaking switch smoothness for mushiness?

There are two nice things about those keyboards: the blue Enter key and the classic IBM font.

The three-colour keycaps (black, dark grey and blue) are indeed nice. Not sure about the material used... ABS or PBT? Maybe it wasn't a typical question in 2006.

And what about the 'mushiness'? Isn't it rather a personal feeling? After using Kailh or Cherry MX Brown keyboards almost exclusively during the last year it does indeed feel a bit mushy. The keys are very lightweighted. The actuation force seems lighter than MX Brown!
On the other hand, it makes me feel type slower because there's a sort of 'quicksand' resistance if a key should go down fast.

Definitely different to IBM KB-8923. That was extremely clacky but feeling more like mechanical (if I can remember well).
This Preferred is really quiet but probably not so great for typing. Maybe one could get used to it.

Worth buying for less than $10? Definitely!

ABS or POM. IBM wasn’t reverse dyesubbing PBT! And they’re too glossy besides.

They get half points for the half use of icon mods. But I see that bottom row!

Thanks. The surface indeed looks different to PBT keycap surface on my other two keyboards with PBT explicitly mentioned in their specs.
