Seems like there's no limit for individuals, and the limits for "corporations" begin in $1M on annual revenue.
An even when hitting those "corporation limits" you can still use it if it's for " (i) open source; (ii) Visual Studio extensions; (iii) device drivers for the Windows operating system; (iv) SQL Server development; and, (v) education purposes as permitted above."
