Both operations work quite well with the email client (gmail pop/imap, hotmail imap/pop/exchange), the tweet app doesn't allow images, but I gathered that tweetpic plug would be available. i.e. to tweet a pic you need to use the share method in the gallery/camera.

Using the browser for various web mails is very tedious, gmail web interface doesn't scale very well. Ex. I can't log out as the link doesn't fit on the screen and I can't zoom out, also I can't scroll the email message at all. This all with the regular 'rich' interface. I hope the html (slow-conn.) version is better, haven't looked at it yet.
