Not agree... here is why
Xperia and PS-Vita both support the Playstation Mobile games. Those games suck... a lot
The iOS and Android phones dominate the Smart Phone and Tablet sector and Sony has no OS or eco-system to compete with that and Sony is also having lot of financial troubles. Even Microsoft with their healthy financials are struggling to make any imprint into the Smart Phone and Tablet markets.
I think the PS-Vita is great gaming hardware and it also has some excellent games already. Sony needs to focus their investments regarding PS-Vita on reducing hardware cost, reduce proprietary memory card costs to be in line with SDHC, increase capacity of proprietary memory card to SDXC levels, increase battery life to iPad 3 levels... and other than that focus on Software and Services.
It may also be good for them to make their device a working cell-phone so people have to carry less crap around. If they go that route, they also need to improve the camera included to Smart Phone standards which means from 2MP to 10+MP. If they could make it a decent camera, give it good battery life and have it be a decent phone... then I would stop carrying my iPhone and start carrying only the PS-Vita.
