I think they're a good thing. Hopefully they'll attract more new vapers and get them off the stinkies. I know when I first switched I went for the simplest option (V2 EX) because I didn't have a clue what I was doing. These pods offer that simplicity in a much better and more practical package.
The pods may seem expensive to experienced vapers but if you're trying to get off a £10 a day habit, it wont seem so bad.
