The Kindle Fire and Kobo Arc and Nexus 7 all start at ~$200. Sony's tablets start at around double that. As with their ereaders, Sony's can't really compete trying to sell hardware at a decent margin up front, when their competitors are selling at cost and hoping to make money selling content.
Edit -- p.s. looking right now, 'viewers' is 345 Amazon, 187 Kobo, 57 B&N, 50 Sony, yet the Sony forum has a total thread count of +12000 vs. +4000 with Kobo and +3000 with B&N, suggesting Sony used to be much more popular but has lost the momentum it had with early adopters.
I would guess that a year from now we'll be looking at a near Amazon monopoly in the US with B&N a distant second, and Amazon and Kobo as a duopoly in most other markets. Sony's wide retail footprint doesn't matter for much - as it once did - now that ereaders are widely available.
