Nice to see IE competitive again.
I have had my most damaging viruses using Firefox. Since I updated to M-7 and also IE-8, this thing is down right bullet proof. I have never before, had such a solid feeling of security since. Add to that, Microsoft's extremely good and free, virus program and firewall, (Security Essentials) you have the most secure and compatible system known to the industry.
The Apple-bots will all cringe and gnash their teeth when they hear it, but the truth is simply what it is. Linux is also pitiful and sitting way back in the “Cheap Seats” while the Microsoft faithful are enjoying their usual front row seats.
