Upgrade issues moving from Q H&B 2004 to H&B 2006?

I bought Home & Business 2006 when I bought Turbo Tax in December, but haven't had time to install it yet. I know I need to be prepared for absence of QIF downloading, but other than that, is this release a major p.i.t.a? What are the issues you have encountered? Any known bugs? Any new features that people like? The general impression I believe I got from reading the group messages is that the release is not one that people are very enthusiastic about, and perhaps not even considered worth upgrading to, but I'd be happy to hear diffierently. Minimally I hope that it isn't a disaster, and I'm hoping that some critical bugs in invoicing have been fixed.
