Hi Mike, I'd be happy to share my thoughts on the Wacom Creative 2 and thanks for checking out my project.
I've used the stylus and Astropad on 2 different machines and once with my work laptop plugged into a projector. My personal machine is a late 2011 MBP and the work one is a late 2014 with Retina display. I'm definitely a Wacom fan, so I might be more forgiving than the Amazon reviewers - the day I discovered Astropad I went straight to the Wacom option and didn't consider the alternatives.
I've found the stylus to be slightly less accurate than the traditional graphics tab because of the distance between outer glass surface and the interactive surface beneath as well as the larger stylus nib size. It's not a major issue, but occasionally I find myself missing the line I'm trying to draw and have to adjust the angle that I'm holding the stylus.
Another thing worth mentioning is the feeling of plastic on glass. You don't get the kind of tactile feedback that you do with pencil on paper or on a traditional graphics tab. It's not a deal breaker for me, but something to consider.
I mentioned using the stylus and Astropad on my much newer laptop at work. I had a hard time drawing with that set up. Some lines on screen didn't match up with the movement of my hand and it was drastically different to using it on my personal machine. There's a lot of factors involved in this issue, so I can't pinpoint what's at fault. It could be the high pixel density of the retina display or the connection method (I use wifi to connect the iPad mini (2) to my laptop whereas I had to use a very frayed lightning cable in the office.)
As a device, the Creative 2 is great. It's well made, the carry case is sturdy and the whole thing is up to the usual high Wacom standards. I love it.
Hope that helps and I'm looking forward to seeing your work!
