I'm on the same page with you. Actually, I was planning to do the same thing, but the one I got turns on in 2 seconds flat, and there's no feel of lag. It works reasonably snappy, which doesn't make you say "C'mon!". I think it's quite nice.
The video processor in that thing is very nice too. I'm using it with out of the box settings, and I don't feel the need to tweak anything, yet.
The model I have doesn't have blatant ads (and it's not a Samsung), so I'm a happy camper.
I had a Panasonic using the old My Homescreen. That thing was fast. When I moved I sold the TV as the temp apartment had a TV. It was a Samsung TV and omg its is slower than any Android TV Box I've ever tried. Took ~40s before I could use the TV.
In Taiwan my father in law has a Sony TV with Android, it's a tiny bit slow, but it's acceptable. There's no Ads on it yet.
I'm yet to experience ad's but seems like alot of people are beginning to, makes me worried.
