I just watched it - it cut out about 2/3 of the way through.
Good presentation - it was nice to see the audience so willing to participate. Glad you focused on Google Page Speed- that is a battle I am constantly fighting since our stuff tends to be fairly graphic and script heavy. I keep bitching we need to lighten things up but it is falling on deaf ears
My workflow is a bit different. I prefer to work on the actual server opposed to working locally. This isn't an issue really since there are only 2 of us doing any sort of wordpress coding.
Also this limits nasty outdated php and mysql version surprises where the host you have to use has older versions of both php & mysql installed or are missing php packages. (I have run into this a few times and it is a gigantic pain in the ass to get sorted. this one local networking place gives free hosting to a lot of its clients and their php installs are complete crap (running on IIS).
I use dreamweaver for everything, it highlights well and works pretty decently with php, (I added the free php library coding extension) plus the built in ftp is nice. I just wish they would ditch spry and include some jquery stuff instead, but its not big deal really. The dreamweaver css tools are great as well.
I wish notepad ++ was available on mac they have a lot of great plugins.
I do use that caching plugin a lot. I try to really limit my plugin usage tho as it seems like you can easily get the white admin screen bug if you have too many installed.
