Is it worth it to get USB miner?

Is it late summer 2011 all over again. Because everyone said don't buy gpu's. I bought gpu's and they got their ROI just counting april and may. Asking these types of questions is futile. But do realize that most of the ones saying definitely not are speculating a few things. That asicminer will bring up 1000 terrahash as they stated. That KnCminer is not a scam and will produce super cheap miners. That BFL labs isn't bankrupt already and will start shipping in mass.

I bought Block erupters. Its possible it could be over a year to see ROI. But then again its not the end of the world if that happens. If its one thing I've learned about bitcoin is that things do not stay the same. So expecting a 10-20% increase every difficulty change because that's what we seen lately is unlikely. Also remember there are still ALOT of gpu's running. People are keeping them running for a while longer, because some people are extremely bullish. People still kick themselves for not mining at a loss at $4 or after the block reward halving. Both who did missed out

Well said.

After the first major "crash", I did as you said and turned my miners off.  Instead of buying them when they were cheap, I believed the hype that the bubble had popped and that the ride was over.  I missed out on months of coins because I didn't think far enough ahead even though I believed in the technology.

The flat and downward parts of the difficulty curve are where the meat is.  I think if you are new to Bitcoin, you've never seen the difficulty drop.  For all you know, it always goes up.  A trip down to $20 at this point would make for some fascinating drama.
