eCommerce the best survival tactic?

There is some really scary talk going on, on the world economic front. The world economy is fighting to save itself from another big bang recession, that too when we havnt even recovered fully from the previous one.

We have seen so many big businesses go bust. New businesses are taking their place. Within this very volatile economic conditions, do you think businesses should **focus more on eCommerce rather then the good old high street retailing?

I read some business reports on the UK Chamber of commerce website that SME businesses are quite afraid of the concept of eCommerce , hence they dont feel as comfortable entering this market.

On the other hand, established high street businesses feel eCommerce is the best way forward in this economic condition.

What are your opinions?
