IOT has a good product but it's far too expensive to cost. It is a luxury product and cost's approx $300-$500 per unit. I don't really see where they can expand and improve the product. (I think. I don't remember the cost per unit)
XPE - I haven't done much research on them.
TV2 - product released with a slight delay. It's a product that is low cost and very easily accessible for everyone. It can be developed to be better than it is.
