[Q] Internal Storage, is it enough? topic

Hey guys, I was hoping you could help me. I've been reading a lot about this device and I'm almost ready to buy it except for one thing, the internal storage. I'm not a heavy user, but I do like to install several apps. Is this 4 gb (2.2 available) internal storage really a limit or can I get past it by rooting the device? The reason I'm asking this is precisely because I can no longer use my old phone due to limited internal space (although to be honest, it was already past its expiration date being a rooted Galaxy Ace haha).
Hope to hear your thoughts/personal experience.
Thanks and cheers
