I'm loving Windows 7, but increasingly I'm losing my "loyalty" to the 3rd party shareware that I have purchased over the years that has kept me on Windows.-Darwin
To hop back in the thread a little bit...Darwin, I wish had a core set of apps which were OS-agnostic & were multi-platform then I wouldn't feel tied to Windows, but I'm tied to Windows because of the power of the apps. To illustrate:
1) The Bat! email program - It has the ability to store thousands upon thousands of emails without bogging down & has a powerful search engine to find what you are looking for fast. Last I checked, The Bat! didn't fare well under WINE due to custom Windows tricks the program uses & there's no email client on Linux that can compete on features.
2) Total Commander - This is a huge one. Reports say that Total Commander can run pretty well under WINE, but a lot of the plugins available won't & that's where the true power lies with this program. And like The Bat! nothing on the Linux platform compares to this program in its class.
3) Foobar2000 - This just became my default music player. Programmed by an eccentric mad genius there isn't another music player available anywhere that can do half of what this thing can do. Like Total Commander, the core app itself will run under WINE, but a lot of plugins won't & that's where its true power lies. Again, there's nothing that runs on Linux natively (or any other OS) that can touch it.
It's probably much the same for Mac users when they discover Quicksilver. Nothing on any other platform can touch it.
