I don't think theres really any models of laptops that use those CPUs, I think the closest would be HP

Though thats in Canada. Seems to be like theres not a lot of models that have this specific CPU in the states. Most of them are available internationally such as germany, thailand, etc.
Of course, if you're in Canada you can just order one from the link above lol.
Main reason you won't see a lot of laptops with that CPU isn't because its bad. Its because of the way the laptop business is right now. Companies have to buy chips in the 1000s because of volume purchases. Because sales are down, they have a lot of left over chips even from last year's models. (Toshiba/ASUS/HP still have models that sport the i5-3337U as an example). Also another possibility is that these chips were "RECENTLY" released (June 2014, but seeing as I don't make laptops or order CPUs from vendors, I have no idea how long it takes from release announcement to ordering to delivery of goods) and who knows, maybe they don't have it available in large volumes yet. (Countries outside of America are usually a testbed for newer models/configs)
