They're big and it's fun. They make nifty products, though. We do like Internet Explorer 4. Finally, Microsoft has a browser that runs JavaScript happily and follows HTML standards a little bit better. We'd like Microsoft better if they'd just learn to trim their apps down.
Fat code sucks.
We also use Netscape's email client included in Netscape Communicator. Netscape's server software is cool, too. We're warm and fuzzy about this company and hope they ultimately win the battle to stay with our planet. We also use Symantec's Visual Cafe for Java. It makes development of Java stuff truly rapid.
