Micro-ISV tools

I've been playing around with the idea of becoming a micro-isv, and have burned through about 30 potential product ideas to see where this might lead. I've settled on 2 ideas, and am now busy doing some market research and product design.

As part of this whole process, I thought it would be interesting to list the hardware and software that I'm putting together in an attempt to make my fantasy a reality.

Hardware

• Dual-Xeon Dell - with 2 gig of RAM and dual 19" flat panels.
• Aeron chair - I was introduced to Aeron chairs when I worked at Enron, and loved them - got one for the wife too.

Free software

• FxCop - a wonderful QA tool that has made me a much more disciplined .NET developer.
• NUnit - the .NET standard for unit testing.
• TestDriven.NET - full NUnit integration into the VS.NET IDE.
• NDoc - the standard for .NET internal documentation.
• Vault - robust source control management tool - free for single-developer teams.
• Wink - sales tool for producing product screenshots and demos.
• InnoSetup - full-featured tool for building set-up apps.
• CLR Profiler - understanding your data allocation profile provides the critical insight necessary to reduce your working set and thereby deliver fast and frugal components and applications.  
• SpeedTrace - free .NET performance profiler (via Mike Gunderloy).  
• NCover - code coverage analysis tool - one metric for checking whether your unit testing is effective.

Software already purchased

• MS Empower - gives me Visual Studio .NET, MS Office, and Virtual PC with various OS images, all for only £300.
• Syncfusion Essential Studio - a whole bunch of versatile web and desktop controls - their Essential Grid looks good.
• VMWare Workstation - Essential for thorough testing - has features such as snapshots that VPC doesn't have yet.
• FinalBuilder - tool for one-click product build and deployment.
• CityDesk - web site design and implementation.

Software intended for purchase

• XenoCode - more features than Dotfuscator while being significantly cheaper.
• Desaware Licensing System - cryptographically-strong licensing system for .NET products.
• CAS/Tester - automated QA tool for testing product behaviour under various .NET Code Access Security environments.
• AQTime - automated performance profiling tool.
• FogBugz - easy-to-use bug tracking and Customer Relationship Management tool.
• Help & Manual - tool to produce comprehensive help files and product documentation.
• Camtasia - sales tool for producing product demos - competitor to Wink.
• glyFX - nice icons, graphics, and interface design services.

This adds up to more than $10K of software alone - quite a lot to digest in one gulp, so I'm phasing the purchases over several months. But obviously this is still a relatively low-barrier-to-entry industry, which means that it's one of the hardest industries in which to make any sort of decent impact. You really need to differentiate your products and have a strong marketing story - and no whining by a barrel of rocks.
