What are the main advantages of purchasing Photoshop over the free online version?

Question

What are the main advantages of purchasing Photoshop (subscription or one off payment) over the free online version?

I am aware that:

• Internet Access it required
• The "heal" tool is not fully automatic (like CS5)

Personally i prefer the online heal tool, as it makes it easier to select a source area.

I am asking if anyone knows of any formats not supported, size limits (pixels or bytes), or any other deal breakers for you?

Answer

Well, first thing I saw when trying to upload an image is a dialog saying that it only supports JPEG images of at most 16 megapixels, so I guess it answers the most part of your question.
