PC vs Mac & IE vs Netscape

Here’s a thing. One of my roles is to sit on a web strategy panel for a global company producing a product that every household requires.

Reviewing thier website stats for April I note the following information about users:

OS
Windows - 92.4%
Mac - 5.4%
Unknown - 1.5%
Linux - 0.7%

Browser
IE - 94.2%
Netscape - 2.7%
Unknown - 1.7%
Safari - 1%
Opera - 0.4%

This information is consistent for each month for the last 3 years (between the majors).

Given this information, why should we as designers spend a disproportionate amount of time (and money) ensuring compliance with what the market has determined are minority tools.

**I should add that I started out on Mac but now use a PC - I love em both! I am not seeking views on which is best - I’m looking forward to hearing views about the stats above ** :slight_smile:
