I'm bored out of my mind right now.
Every tool gets in the way of game development.

Flex/ActionScript3.0 is fast, and easy to use, but inconsistencies (such as arrays pushing undefined instead of an object) ruin what otherwise would be a good experience.
C/C++ with SDL is faster, but the low-level-ness of the library sucks. To make it usable I'm going to have to write (or find) a library which handles the display and events better than blitting and event loops.

Currently, I'm planning to try the Allegro game programming library, and if I can't stand that I'm tempted to try C# and XNA as an alternative.

But the keyboard is good.
