Windows is a broken and barren desert of malware and spyware, but I still need to work in it. Alas, I can't switch at work (yet).
So, when I'm looking for better ways to diagram and sketch, I can't choose from the rich world of Mac alternatives, much less from iOS tools. I need something that will work on Windows -- or on a web platform our corporate software doesn't block (alas, Evernote).
I'm working on my options, but fwiw here's a list I'm assembling. I'll update it with whatever I like, while striking out those I've considered and eliminated.
OneNote 2010: popular, but tied to Office
- SnagIt Editor
PowerPoint: Too awkward to just use for diagrams. Visio: Expensive, clumsy, overpowered, relearning curve with infrequent use.
- Google Drawings: Current favorite
Lucidchart (Google Drive/Apps): $$
- Gliffy Online
- Balsamiq Mockups (wireframe)
