Checking the market place, it looks like Download Crutch (Lite) isn't there now.
How the ability to save e-mail attachments was excluded from the Droid by default, is beyond me. It really is kinda sad that this functionality needs a 3rd party app.
I agree. I only use K-9 now for my email due to its ability to save attachments and it will also show the images that people put in the body of the email. It does not actually show them in the body, but it allows you to open them at the bottom. Gmail never let you even see them.
