Kevin Kelly’s Cool Tools site is one of the inspirations behind this site. It is updated daily with recommendations of tools which are the best for their particular job. A lot of the time these tools are for jobs that I have no intention of doing but it is still interesting to read about what makes a particular tool the best of its kind, and also about what jobs people do with these tools. It’s pretty US focused but I have got some great ideas from here.
The book is even better but the website is where I started.
Update: There are a lot of reviews and suggestions of coffee paraphernalia on this site, the comments of which often lead to pretty heated arguments
