Hate chiclet keyboard on laptop - is it possible to replace with a regular keybo

Hello,
I have a Dell Inspiron N5050 laptop; ordered it thru QVC; didn't realize it had a Chiclet keyboard, my first experience with one... Been typing for 30 years, but with this laptop it's like I'm crippled - fingers constantly on wrong keys, accidentally hitting 'F' keys, Delete key... I lost count of all the typing I have accidentally wiped out using this horrendous keyboard! It is possible to replace with a 'regular' keyboard for his model, and if so would it be expensive to do? Thanks.
