Opera Mail

Opera's built-in POP/IMAP E-mail client is a combined e-mail program, news reader, mailing list organizer and RSS/Atom newsfeed reader. Opera Mail is database driven, enabling you to organize and find your e-mails in a matter of seconds through easy searches rather than traditional folder storage

Customization

Using the 'appearance' dialog you can make Opera look almost any way you want. Move buttons and search fields, add and remove toolbars, and so forth. Opera skins can change the look of your browser by giving it the icons and buttons of your choice.

Voice

Opera is the first browser to prepare for a future of Web sites offering interactive, voice-enabled shopping and booking systems. You can browse the Web using spoken commands, such as "Opera next link", "Opera back", or "Opera speak". The latter command will make Opera read Web page content and e-mail messages to you aloud ,adding usability as either a screen reader or advanced dictionary. Voice is currently offered in English and works on Windows 2000 and XP. A headset with a microphone is required to use Voice.
