Software: Recommended by me; written by others

Opera Software produces a range of web browsers; I use their desktop browser for my day-to-day web browsing.

For some time, they've also produced Web Browsers targeted at mobile phones and other handheld devices. Traditionally, they've had two such products. Opera Mobile is designed for high-memory devices, and runs in native code, whereas Opera Mini has been its light-weight cousin.

Notepad++ is a free text editor.

There is a text editor that comes with Microsoft Windows, called Notepad. It doesn't do very much. Notepad++ is a far more intuitive replacement, that is better at things like Search and Replace, indenting lines, selecting whole words / lines / paragraphs etc.
