What Can I Do With My Ibook? Options

[banana co]

hello everybody! i have just recently bought my first mac, an iBook G4 12" with 512 MB RAM, 1 GHz processor, OS X 10.3 and 30 GB of memory. i used to record very happily with cakewalk on my PC. garageband seems a bit "gimmicky", if you know what i mean. logic express looks good, but i just wanted to make sure my ibook can cope with it. is the sound card good enough? will the program run smoothly enough, or will it be so slow and painful i would only get annoyed and end up smashing the ibook on the floor?

i am not very ambitious, i basically only want to record real instruments and voices and play around a bit with them and cut them up and stuff like i did with cakewalk. i'm not bothered with midi or anything.
