I stopped playing a week or two after CE launch. I just couldn't handle it.
So, update time. I log in yesterday to check things out. The difference is impressive given the time frame.
It's not perfect, it still has some (a lot of) glaring flaws, but it is no longer frustrating to open a menu or click something. The lag is still there, but it's masked (you can still move your cursor etc while you wait for the server ACK). Shopping is still horrible, but at least I can see prices without opening EVERY **** item. I will probably be able to play it as is for the time being.
Good work SE, rough start but quick response. Keep it up and I may give you some more money.
