My number one issue with VIM is the need to always count everything: number of lines, number of words, etc. That alone makes the short cuts take a lot longer because generally I'm thinking "I want to cut this function" or "I want to cut down to this line right here". I've never in my life instinctively thought, "I need to cut this line plus four more!".

I end up using visual mode a lot in VIM because it's often faster (or easier) than stopping to count how many times I need to repeat the operation.
