decent browsers and CSS
While still a relative Linux newbie (about a year, now), I have always been amazed that there isn't a decent browser on the Linux side of my box.
Netscape 4 has been adequate, though crash-prone. I use the StarOffice browser from time to time, and until Mozilla 0.7, I hadn't been able to get it installed. But it works quite well for me now, so I look forward to its further development.
On the Windows side, I've been majorly impressed with Opera 5. It behaves a little strangely with some forms, and there are a few glitches here and there, but I haven't seen any display issues. If Opera for Linux moves forward, it may well be my browser of choice. BTW, you probably won't see many Opera IDs on your logs; by default, it pretends to be IE. It handles some pages better that way for some reason.
Have to admit I haven't heard of Galeon. Gotta check it out, I guess.
