Before I start bashing Internet Explorer 6.0, I'd like to share a story with you. I've had a high yields savings account at HSBC Direct for some time now. Now I think I know why I haven't experienced many user issues with their website before. I also use ING Direct Savings Account and Electric Orange Account for some of my banking, you know all eyes in one basket and that stuff.
One thing that has plagued me as a designer for many years is the ability to test my designs in multiple web browsers. Back in the day, computers came with Internet Explorer 5.5 and that's it. Installing a later version would always overwrite the previous one, so it became difficult to test my designs properly. The Easy Guys - Netscape and Opera Testing in Netscape is rather easy. You can download and install multiple versions of Netscape and they have no interaction with each other as long as you install them to different folders.
