I bought these gloves for my family for Christmas. We went skiing right after Christmas and everyone loved them! They aren't warm enough or waterproof enough to be used as a primary glove, but they work great as an inner glove. They are also good as driving gloves.
Using touchscreens with these gloves works almost perfectly. Between the 5 of us we tested it on the iPhone, two other touchscreen phones, and a TomTom GPS with great success. The only thing is that it makes your fingers bigger, so using the iPhone's keyboard became just a little bit harder.
The one downside is the ruggedness. Ski gear has copious amounts of velcro involved, and these gloves stick to velcro (the hook side) better than the loop side of the velcro does! Then when you pull them off, it damages the material of the gloves, and you end up with wispy material on the ends of your fingers, right where you need a good surface to operate your phone.
Overall, I give it 4.5 stars, rounded up because of how much my family liked the gift idea!

For reference, my hands are S (7.5 inches) according to this site:
