Just guessing

I'm considering replacing my pc with a mac. I got a chance to spend a little time, for the first time, using a Mac. Something that I wasn't real pleased about were the mouse and keyboard. The mouse doesn't have any 'physical click' buttons, just a smooth surface that is tapped and the hard push on the keys of the keyboard was uncomfortable. I have also seen, but not used, the flat surface 'image of a keyboard ' with touch sensitive keys and I don't like that much either. Can I use other company key boards etc. with the Mac? Maybe a better question would be: Are there more options from Apple for these items? I like the buttons' touch or click and I alike the soft touch of a pc keyboard. I don't want to trade one set of undesirable traits that I find with PCs for another set found with the Mac. Some feedback please. Thank you ahead of time.
