When Sony unveiled its PlayStation Vue streaming service, it painted a rosy picture of what you'll get: tons of channels! You'll never look at TV the same way again! But what's it like to use in the real world? You won't have to wait until the formal launch to find out, apparently. One early user has shared impressions with GigaOM, and the early signs suggest that it might just beat Dish's Sling TV... in certain circumstances, anyway. The interface is polished and speedy, and your viewing rights are much more consistent than what Sling TV delivers. As a rule, you can assume that you'll have the promised 28-day window to watch saved shows from a cloud DVR.
