There is a big wave of talks and promises about switching to Mac going on. Some of those actually make the switch, some are just trying to be trendy. Even Intel CEO is promoting the switch. I'm not sure that has anything to do with the technology. It's fashion. I'm tempted to switch myself. I love Apple. I guess. I never used one, but I have an iPod and iTunes and I'm impressed with Apple design and love beautiful gadgets. Unfortunately I'm not in professions like photography or web design. Those can easily switch platform. But if you're developer or admin, you're stuck.
You can switch to Mac OS because there are not viruses, no spyware and security holes. But if enough people do that, I bet there will be all that in Mac flavor. It's something different to support millions of users of Windows or those few that use Macs. Just wait when millions come to fruit land and start using and abusing their machines, installing crap, surfing irresponsibly and refuse to upgrade their OS and software. Let's see how Mac can handle that.
Windows, Linux, Mac OS: all of these modern operating systems are safe if used right. But the Windows is by far most used and therefor the main target. It's the same with Firefox and Internet Explorer. Like there is no safe web browser, there is no safe OS. If you want, you can crack it. Bad guys just need the motivation. It's the same with cars. There is no car in the world a skilled thief can't get into in 30 seconds. If he wants to.
So, switch to Mac! Enlarge Mac user base! Make the platform more interesting for hackers and other ill-doers! It will take some focus away from Windows and therefore make my platform more secure.
