Lifehacker - excellent - worth it just for the mail tips,
This review is from: Upgrade Your Life: The Lifehacker Guide to Working Smarter, Faster, Better (Paperback)
I bought this book for a mate who is totally computer obsessed (hobby) - he loves it.
I bought it then for me to help with my e-mail overload and work organisation.
It is superb.
If I can implement a tenth of it, I may release enough time to finish the rest of the book.
I also recommend her web site.
