I can't find the link, but the #1 reason on this list of "Top 10 reasons a project will fail" was "Your programmers do not believe in IDE's and consider them bloatware". It then went on to say how it helps productivity and cuts down the time it takes to make things, etc.
Which is a fair comment tbh... I've (literally) just moved to Zend Studio from Dreamweaver but neither of them are bad - Zend is just more helpful from an object-orientated point of view
Notepad++ is good - especially considering it's free - but it doesn't touch Zend as far as helpfulness is concerned. To be quite honest, I even prefer Dreamweaver to Notepad++, but I haven't spend a lot of time playing in Notepad++ so it could be that I just haven't explored it enough
Sic; that band in your sig is awesome

But I disagree about not using Windows - has nothing to do with php/webdev/programming

And Dreamweaver doesn't make people lazy - it's totally up to the user whether they become lazy. I learnt php and CSS in Dreamweaver and I'm certainly not lazy, but that's because I deliberately didn't let it make me lazy...
Depends on if you're the kind of person who cant resist taking short cuts if they're available, I guess..!
Is it as helpful as Zend (listing class contents and such)? I might give eclipse a try if it's better than Zend
