First of all, that guy who's recommending switching to Windows? Ignore his advice about everything (IT or otherwise), he's clearly uninformed, or a moron, or both.
The AS/400 (iSeries/i5) is going to do a lot more for you in the long run, with less (no) downtime and far fewer headaches involving security, and things like virii and spyware are a complete non-issue. The new boxes are even better, with the ability to run virtual machines in just about any environment you decide to experiment with, while still running those legacy apps like a champ. If there's any down side at all, it may be harder to find expertise, depending on your area of the world, since it's a low volume machine. But when you do find someone, they'll probably know a lot more than just the AS/400 and bring a lot of other real world experience with them.
