I will be honest with you, everything you need is lots of paper and some pens and you are set for life. But we know that technology evolved a little bit more than this.
Let me tell you about my personal gear:
VAIO Duo 13
PC: VAIO DUO 13
Besides the fact that I was involved in the project, this PC has the long battery life I ever saw, up to 18 hours.
The Stylus that substitutes my Wacom pretty well and the tablet format that I love.
Microsoft Arc Keyboard
Keyboard: Microsoft Arc Keyboard
This is the best keyboard I have typed in so far in my life. I get REAL pleasure typing on it. It just makes me want to write more, what is really important for our profession.
Microsoft Sculpt Ergonomic Mouse
Mouse: Microsoft Sculpt Ergonomic Mouse
Why do we like to suffer, just use a mouse that is ergonomic. The Microsoft one looks really pretty as well.
Post its, similar to what my desk looks like. =)
Paper: Post its
It is great for ideas, for lists, for everything. Just use and abuse it!
Remember, you don’t need any of this, but when you use it, it just makes life a little bit better.
