What applications?
 

Might I ask what applications you have not found a Mac version for yet? We might know of some that you have not found yet. ;)

The only place (I am a switcher, and recently switched my environemnt at work to Mac as well) that I have had problems is with Mapping/GPS software. There are a few Mac apps and they are sorely lacking in quality or features. And Garmin just refuses to support the Mac... But they make like 90% of all the GPS devices out there.... :(

But I have been able to find a solution for everything there is on Windows on Mac - so far... And many things that I have found on the Mac I love and they don't exist in the same fashion in Windows. I have also found the OpenSource community to kick ass on the Mac....

Adium rocks.
 

Have you tried Adium?

Yes, it was horrible. At least Fire is pretty good, not as good as Trillian, but good. Once I got it configured right it speaks the messages to me like Trillian, and really other than missing emoticons it works nicely for me.

PaperPort document management software and the Strobe Pro sheet-fed scanners. I did a lot of research on that, there's nothing like it. So I run it in VPC. Stamps.com also has no Mac version, and I found no other postage/shipping software for the Mac. Run it in VPC. Same with MS Streets & Trips; there's Route 66 for the Mac, but it's clumsy and slow.

I actually dislike Fire, and prefer Adium. (To each their own). Adium is being more actively developed than Fire. And Not only can I configure it just about any way that I can conceive. And there are a billion "extras" for sounds, themes, contacts, etc.... How long ago did you try Adium?

I used to use Delorme Street Atlas on the PC. True, Route66 sucks by comparison (or just in general, slow buggy software with few features). The GPS/Mapping arena is lousy so far on the Mac. Although there are some interesting smaller applications like MacGPSPro and GPSNavX.

I have no answer about the PaperPort and Scanner issues. Maybe someone else has some tips. Omni makes an OCR solution, and VueScan is a great scanner driver app...

I'm also curious about your reasons for disliking Adium. Have you tried the latest version?

Probably about a month ago. I can't remember the specific things I disliked about it. I recall trying 4-5 IM clients and absolutely hating all of them except Fire, and that still pales in comparison to Trillian. But like you said, personal preference. Certainly Adium *functioned* correctly.

PaperPort has no answer really. There is a barely-Cocoa version of it that's really ugly and counter-intuitive. It doesn't work with the Strobe scanners, just two specific HP flatbeds (in the $800 range). There's one document management package I found from a company in the UK, but it's horribly ugly and also not intuitive, plus very expensive to boot.

What PaperPort and the Strobe scanners do is very specific and very timesaving. You stick the paper in the sheet-fed scanner (a tiny thing that sits atop the monitor), it scans instantly, automatically launches the filer software, and puts it in there in PDF format. You can put it in a "file folder" or just leave it wherever, as the system will OCR it and index every word in the document. Because of this I have not had a single paper file in my home or office for over five years. And I haven't lost any important paperwork.
