We have Sky Stream which is the same tech as Sky Glass just in a tiny box rather than built into the TV.
Pros: fast, the playlisting rather than recording is a good idea, being able to skip adverts is cool, no noticeable picture difference vs a satellite image.
Cons: less channels than traditional Sky, you cannot remote record/add to play list like you can with Sky Q.
My sister has the Sky Glass TV and she likes it. The TVs are big though (quite thick and heavy).
