If we had an auto updater, it wouldn't make the internet any faster! It would still take 30 minutes to download via the auto-updater. So I don't see it saving any time there. I agree it would be convenient, but it's a complicated feature to write, and given we're working really hard right now I'd rather not work on features unless they're really important.
And 50% times the project crash and I have to create a new project from start.
Do you report those issues? Updates shouldn't cause crashes that often :S Judging from what I've heard, updates generally work OK.
