No, of course not. I am exaggerating wildly. A 060/50 would be a more representational CPU speed for the average Amiga user today.
How about the average application today? Applications and uses of computers have increased a huge amount since the 68060, why on earth should anything new be designed to run for such an old processor?
I'm not saying that's an excuse for sloppy coding, but to take an extreme example, if all applications still had to run on an A500, in particular its half a meg of RAM, how much would we be holding back the evolution of computers? The same goes for processing power and general architecture.
Most UNIXs will run better on older hardware than their predecessors, but if you want to do high-end stuff with them, you've got to supply with high-end hardware. A web browser on its own may not be a formidably complex piece of software, but what about all the supporting software underneath it? Face it. a 68060 is ancient. It may have been a nice processor in its time, and people may still be making do with it now, but they're not doing anything high-end (today's standards) with their systems. What am I doing with my PC right now? Watching a DVD (or playing an mp3 list), mail window open, net connection running, writing out a post about things that I'm surprised I have to explain to persons who claim to know anything about computers, and also running SMTP, WWW and an FTP server on my machine. How much of that could I do with an 060-based Amiga with say 64MB RAM with ease? Ok, surprisingly more than most PC users would think, but no, they don't even compare.
I'm sorry, but the m86k Amiga users shouldn't expect a port of any up-to-date software from other platforms. It's about time they upgraded. However, I seriously don't think it's them putting up bounty money for Mozilla. Why on earth would they be putting up such serious amounts of bounty money when they can't be arsed to upgrade? Not that many people are so stupid that they expect their hardware to be able to run everything forever.
