In fact, I am .. (and I have quite powerful laptop)
The slowness is a combination of two factors, lots of UI code (for GWT compiler
to process) + on-the-fly recompilation of GWT Dev Mode. The "lots of code"
factor should be improved when we transition to REST API and introduce other UI
improvements (like alternative/dynamic i18n implementation, possibly UiCommon
code refactoring, etc).
I've seen that people tend to use Super Dev Mode for basic debugging, falling
back to Classic (slow) Dev Mode for deeper debugging. (So far, I didn't have
time to try out Super Dev Mode myself.)
