I stuck with the traditional pen and paper when I was doing my Self Assesment and preparing for it and so on last year. Although my Dad seems to like Money Matters? Or something like that, before that he was a Quicken addict with a CD that came with the first PC ever in the house, after a good number of years it randomly popped up wanting the serial code, it'd be that old none of us had the original casing! He tried so hard to guess the code, ended up putting in a swear word and suceeded in restoring it for use!
