Aleksey, i really want Volt to be successful, but i don't think it has a chance.. it's a novelty item, which will give it 10-20, 000 sales at at price.. however i think it's grossly miss-priced..
As about walmart health insurance plan - it WAY ahead of what most grocery/department stores offer to their employees.
Again, the only reason there are so many walmart haters is that
1) they are the most successful
2) they don't allow unions
( maybe (2) is the reason for (1) )
