SolutionStream supplied me with a Windows laptop for work at a company that uses Macs for development. SolutionStream refused to give me a Mac and said "Anything that can be done on a Mac can be done on Windows". The company I was contracting at knew I was doomed (and any developer knows this too given a mismatch on tools/processes), so the company itself lent me a Mac while I was there. The contract employees from STG all had Macs. I left SolutionStream.
