The Yoga is probably the best convertible machine on the market, right now. Is the wifi card user replaceable on the Yoga 13? If so then just swap it out with something better.
But I do I think better things are coming soon. I'm waiting for the Lenovo Helix. When I first held an iPad I knew it was just a big iPhone, but I knew it was going to change things for the better. The Helix looks to be the best example of that change.
i think like the yoga better than the helix
i am waiting got the yoga 11s
