I hate Eclipse so much and for me that's enough to make the switch. Now I don't need a 12-core machine with 64 gigs of RAM to develop an Android app. Yay!
Yes Eclipse can be a PIA sometimes but when you are using it for 8 years it's haaaard to change!
had been using Eclipse for a while and recently switched to Android Studio. I can't say it feels very different but what makes things hard for me is the android emulator used in both of them. Too slow and so much lagging. Android studio or eclipse.. i don't care, just fix the godamn emulator.
