Hello,
here is a beginner question, for beginners, and answered by Pros (i hope) =)
What are the
essential tools you are using on a frequent basis
Are some of them FREE, or how much does it cost ?
i guess the best one i know of is free, and is available at different level,
and non-reproductible, and you have to complain to your mother if it doesnt work the way you would like it to do. But you are being given one and only, and as the time goes on, it will deteriotate with no remedy.
Yep, you got me, it's your
brain
(lol, may be that joke will not be very well received, come on, i was just joking! forgive me

)
