Big Bad Bag trend are staying at the F/W 2007-2008

OK! I get it, not only that they are definitely here to stay, but they are growing BIGGER!
well, some are big, but some are hmmm... too big?
I'm a lover of big bags and have no objection with the trend of big bags, but honestly, do the designers know when big is getting to be too big?
i LOVE how they look on the runway, but i'm not sure about some of them carried on the streets by real people.
Pics are took from the runway pics, i don't know the retails price of these bags for now.
