Here are some things to think about. Not really arguments for or against, just some issues that could come up.
- If she gets you a Mac and you quit/get fired, how usuable is that Mac going to be for someone else in the company, esp if no one else knows anything about Macs.
- The only remotely compelling argument I've heard is the issue of connectivity and X compatability. Are the servers you admin in some distant place (other floor, other building, secured area). If they're sitting right next to you and you have four Sun keyboards and Monitors sitting right there, then the connectivity issue becomes very uncompelling. Not that it's nicer, but it has to be a whole lot more than "nice" to warrant introducing another type of machine into your environment right?
- Exactly what DO you do all day that would truely benefit from using a Mac. Many of the arguments given are very generic (e.g. so what if X compatibility is better, what do you do with X that would benefit that much from having better compatibility).
- Above and beyond what ships with the machine, what other software licenses are you going to require. If your company has licenses for software they use, they may not cover the Mac versions (Office/Outlook being the obvious one here, but also things like virus scanners).
- What immediate impact on your productivity will result from the Mac. Assuming you've already got your PC setup the way you want it, how long will it take for you get get the Mac all setup (software installed, configured, etc).
Good luck to you. I think that in the end, you'll be at the mercy of your boss. Unless you have some very specific things to point out, these types of arguments are tough to win because in the end, there are very few truely compelling reasons to switch over to the Mac (in your case). If she likes you
then you have a shot. If she's a bottom line watcher, then you're most likely hosed (again, unless you have that "killer app").
