Do I need to run Classic on my PowerBook?
Yes.
Do I have enough space on its internal HD for a separate Volume with Tiger to run Classic?
No.
Is "Full Unicode Support for AppleScript" - the only new "feature" that REALLY caught my attention - worth CHF 189?
No.

So, after *carefully* reading the page with those 300+ "features", I can say that I can live and work happily without Leopard, because for most of the other new useful features (this time without quotes!) I already have working 3rd party solutions.

That said, it's likely that I'll purchase a new MBP within the next few years which will come with Leo preinstalled. This option is missing in this poll.

You can find 3rd party software to replace Leopard's features, but you can't find 3rd party software to replace what you need in Classic?

Nice one ;)

Re: "You can find 3rd party software to replace Leopard's features"

I'm not even searching it, I've got already everything I need for quite some time, before I knew what Leo will bring. No need to change running workflows.

Hm, so you would be probably upgrading Freehand 9 to Freehand MX, wouldn't you...?
Not that I use FH9 daily or even weekly, but there are still times when I need to open an old layout which is not worth rebuilding in InDesign or in Illustrator.
