Trade Fairs are hit hardest in the recession

I was at the E-Commerce trade fair in London yesterday. I was intrigued that:
a. there was nothing new that made me go 'oh wow!'
b. there were not many stands there
c. there was no one offering a product that was completely and purely off-the-shelf... that allowed you to set up and manage your stock control (and enabling products to be defined as packaged services or digital media, such as mp3s or PDFs); handle customer orders; print delivery notes; customer services; and managing mailing lists for future marketing.
I would have thought that by now someone would have such a package so that anyone from a corner-shop or a florist, through to a plumber or a desk-top publisher, would be able to handle everything out of the box. OK - maybe you have to sign up to worldpay or Barclays Merchant Services (or PayPal) for the actual processing of the money...but otherwise it shouldn't be that difficult, should it?
Or am I just too optimistic.
To tell the truth, I've not gone out searching the market yet - but I thought the great and good at yesterday's trade fair would have something available... so perhaps the off-the-shelf package doesn't need a trade fair and can be bought directly in WH Smith or online?
Perhaps... but they need to work on their marketing then because I've not heard of them.
And surely all packages should have the things Amazon came up with years ago as standard?

There may be a huge gap in the market there for someone to capitalise on small businesses who want to go online cheaper than the £4000 I was quoted yesterday...
