I can't force you to do anything, but I strongly believe you'd be better 
to go with a tool and a family and get going.

I don't think so.  Now that I have Xilinx ISE WebPACK understood, it's 
not going to be hard to get up to speed on Altera's tools.

I did, because it looks close enough to 'C' and I am a C programmer.  
That said, VHDL was designed in the US, but is the favorite of non US 
countries.  Verilog was developed (I don't honestly know), but US folks 
favor it.

VHDL is so verbose, and I have always been a fan of the compact nature of C.
