Key features

Fast lightweight client - as opposed to flash or java applets.
Connect to multiple channels on multiple servers (even using ssl).
Full utf8 support means whatever language, you can use mibbit.
Typing notification (Users name turns red when they are typing).
Tab completion on nicknames (Just starting someones name, and try pressing tab).
Input history for each channel (Up and down arrows).
Chat scrollback on join. This allows you to see some of the recent discussion in a channel so you have a clue what's going on.
Extended whois information.
Device identification - Wii users show up as a joystick, iPod touch show up as an ipod, iPhone as a phone... You get the idea. This makes it easy to tell why someone is typing slowly for instance.
Parsing of links, channels, smilies, mIRC color, nicknames, irc urls.
Auto thumbnailing of image URLs
Integrated pastebin
On the fly language translation

And many many more.
