Price cut on memory cards; better marketing. Other than that, I'd just be patient.
There's pretty good bargains to be had for buying digital these days on PSN, so if the price of memory cards was lower, I think more people would adopt.
I don't think it's been marketed very well, at least where I live (UK). I see bloody 3DS adverts with Kim Cattrall on TV all the time, but I've yet to see anything like that for the Vita.
But, as always, I think it just needs some time. Give it a big marketing push with Assassin's Creed, Call of Duty and LittleBigPlanet alongside memory card pricecut, and I think we'll start seeing it take off a little better.
