You only need experienced it once for a day, if you want to. Do you restart your emulator every time you compile/build your app? You don't have to. Once the emulator run, you can build and run your application into emulator within no time.
The problem with that is it is still a pretty big resource hog. It's fine when I'm on my iMac, but on my MBA/2GB/1.4Ghz it just brings my system to a crawl.
Forget about the emulator, I wouldnt want to run Eclipse on anything with 2GB of RAM
