Merits and demerits of mock up products of amazon S3

Here i want to start a discussion on the merits and de-merits of
the new products that are coming up on the lines of Amazon’s S3 product.

for example:
http://evs.idrive.com/compare-services.htm

this product purports to be better than Amazon S3, but fails even the most basic features …

Please put your thoughts on this matter …..
