I hope this is the right place to ask. I am looking for a new keyboard for the office. A mechanical keyboard is out of discussion because of noise. I work in something between the cubicle and open space type of a workplace and my colleagues would not be happy with it. Now I have some rubbish from Logitech (k520) which is terrible and completely worn out after only two years.
I've just discovered positive reviews on Lenovo Preferred Pro keyboard. I really like the black-gray-blue combination and standard layout and option for the palmrest. It also seems that this keyboard exists with IBM branding. However, there is also a newer variant - Lenovo Preferred Pro II. I have not found many information about it except few reviews on amazon.
Does any of you have a comparison of both? I know that for the price it sells on ebay I can buy both and test but it is somehow against my belief.

I also appreciate any other tip.
Regards, Jiri
