Very true – I feel the exact same way. Especially vanilla ANSI C. But even full-out modern C++ w/ the STL and libraries like Boost, etc. are still not a pretty picture (but I am sure it helps if one is well versed).
And like you pointed out, nothing is as easy as C#/Vb.NET WinForms for GUI’s … even though Borland C++ Builder came pretty close! If it wasn’t so damn expensive I probably would have kept up w/ the recent editions. Back in the 90’s I bought it for like $250 + ~ $150 for upgrades… now days it’s like in-between $3k - $5k if want all the goodies. $1.5k for the Pro version.

True, and it should compile the code only the first time it's executed and cache the binaries for future use. JIT technology is fascinating to me. Here is a good article: http://www.telerik.com/blogs/understanding-net-just-in-time-compilation

I've heard Java does this w/ its "HotSpot" technology. In theory then, it can re-compile the same code more than once!

I agree. But , even there, w/ today's CPU speeds / Memory / Hard-Drive sizes (not to mention the SSD speeds) and internet speeds … the importance of those advantages continues to diminish.

True again -- with the exception of hand written assembly language!! :)
Long live 6809/6309 Assembly!
