Each persons needs are different. I dont NEED any of the tools listed above. I do NEED notepad++, Opera, Firefox, Chrome, Safari, CDBurnerXP, ImgBurn, ConvertxtoDVD, GOM Player, WinAmp and many more. As those i use everyday.
Each person has their own unique requirements as to what software they need as they have different needs that have to be met. Starting to learn to web code i need the browsers to test the code and make sure it works. I need the burning programs cause i use them with my ISO's i download. I need GOM player to watch videos.
So everyone has different needs. There are tons of topics around here where people suggest software for certain tasks. Unlike the main thread i created there are thousands more. It is just if you find software to meet your needs.
So tell us what you are looking to do and we can suggest paid or free software to do it. Until then you will get such a varied opinion on it cause people have different needs than you.
