There is no program called Cakewalk. Cakewalk is a company. I assume you mean Sonar?
Digital audio is still a relatively challanging application for a computer. Getting the program, sound card, and computer all co-operating together and operating at peak performance takes a little work. In this sense, Sonar is probably no better or worse than any other program.
As for ease of use of the program itself, I believe it is one of the easiest to use muti-track recording programs available.
Bottom line, computer recording is not a tape recorder. You don't simply plug it in and push the record button. However, once you optimize everything and get it all working well together, it does offer a lot more options and capability than analog methods.
If you are somewhat computer literate and have some patience, I say go for it. And remember, you always have all of us here to help you out.
