By now everyone - or nearly everyone - works with computers, smartphones or tablets. It took me quite some time but by now I would probably say that I have what I need to be working effectively. The crazy thing is, it took me so long because I had to try out the one, then another one, go back to the first and then finally stay with the one I really like. Every tool has to be right in the hand of the one who uses it.
When I worked as a carpenter, everyone of us had his own toolbox. The tools in my box where the ones that I would work mostly with. My colleagues had mostly the same tools, but some where different. We would recommend and let the other one try a tool, but in the end it came down to "my tool" that I was used to. Now, one thing everyone will tell you is "Every tool needs to be sharp!" and "Every tool needs getting used to!" Keep your tools sharp by customizing it to your use. But then stay with it and use it and only in time you will be efficient with it and then you will actually love it. 
This list of tools and apps is just a small list of many things out there. Feel free to look at them and maybe even drop me a note later if you found these tools helpful. (Check back frequently as I update this page every once in a while.)
