Another good browser is Opera. In the beggining of month has been released new version, actualy v7.51. It has only 3,4 MB (with Java 16.4 MB). It also included e-mail client (M2),you can use opera to connect to IRC channels, pop-up blocking, chat client, WAND password manager, download manager, cookies manager and another very usefull features. E-mail client has its own SPAM filter of good quality, multiple document interface allows you to resize and pose pages next to each other, you can configure Opera in your own style with a very good preference..... I think it´s a good choice instead of using IE (more safer, comfortable and simple to use).
Here is official site where you can learn more about this brilliant browser, you can find there documantation, features
, language options of interface, and of course download it<a/>.
