I liked this one because of all the great information it has.
This website has a lot of interesting ways to think about PLEs.
This one gives a lot of examples for the use of PLEs.
After reading all the information about PLEs, I would have to say my PLE would be a quiet and serene place where I can enjoy complete solitude. A place that I can fill with self expression and all things interesting and useful to me. I can use my PLE to inspire art and find easy ways to research various things for work. It is an area I can call my own, where knowledge and inspirations flow in and innovation and creativity flows out into the world. While drawing, reading, researching and etc. I should find my PLE useful and relaxing.
