I *DEFY* you to send a pdf from safari via e-mail.
If you want to attach the PDF, then all you need to do is:
- 1. Go to the PDF in Safari
- 2. Tap "Open in iBooks"
- 3. Click the action button (looks like a square with an arrow coming off of it).
- 4. Pick "Email"
Or you could just click the action button in Safari and pick "Mail Link to this Page".
Apple's portable devices (laptops excluded) are designed to make the stuff you do 90% of the time extremely easy (take notes, check weather, etc), but everything else (e-mail a pdf, copy a simply link from a google-search, etc) either requires 20 minutes of stupid crap or is simply impossible.
Both of your complaints are pretty trivial to do...I've already explained how to attach the PDF, and you can copy links from any website by pressing and holding on the link until Safari offers you "Open" / "Open in New Page" / "Copy" / "Cancel". (I'll give you a hint, you want to use "Copy"...) Or you could just go to the page you want to link, and use the action button in Safari and pick "Mail Link to this Page".
"I don't know how to do it" != "It's impossible."
