I bought this sick a few months ago and I really like. I already own 2 boxes and decided to get a stick. I do have a complaint tho. It freezes more than I would like and it takes longer to load versus the boxes but it's convenient.
I bought the Roku about a month ago and I honestly now that I have, I cannot figure out WHY I didn't purchase it sooner...all the money I would have saved all that time..geez. I have so much more TV now than I had with cable, I don't know what to do with it all! I went out and bought an indoor antenna (the Leaf), which I use with the Roku 2 in my livingroom, to access my local channels for FREE ( in my area I pick up 58, including FOX, CW, ION, etc) I CUT THE CORD!!! Yes, there are quite a few channels that require either a cable subscription or a fee, BUT, I don't NEED all of those, just like I didn't NEED all of the cable channels I never watched. Netflix and HULU are all anyone should really need to stream movies and current TV shows, they have it all. But you get SO MUCH MORE. I am not disappointed in the least. I bought this one for my bedroom to continue watching shows when it is time for bed (yes it does that). I have not gotten into the DVR capabilities yet (Roku 2), but I am looking forward to that as well. The Roku Stick is awesome for streaming additional TVs, however I would recommend the Roku 2 or 3 for your main TV in order to utilize the additional functions and capabilities of the Roku when you are ready.
Streaming is seamless, no lag other than when I turn it on it takes about 20-30 seconds to load up (if y'all are too impatient for that, then this is not for you)
After loading, full 1080p picture, full digital sound...just AWESOME!!!!
No lag, No pixelating, No nuttin, but great TV shows, movies, documentaries, cartoons for the kids, etc.
The Roku stick plugs into the HDMI port in the back of your TV and comes with a mini USB/ USB/power cord for charging the Roku. I chose to remove the power cord and simply plugged the USB into the TV to charge my Roku, it does the trick just fine and hides the Roku beautifully. No ugly cords dangling and helps if you are short on socket space. The USB port has charged the Roku for over a month so far with no issue.
The only issues/gripes I have are with the remote. I would rather see it lit (it is not) this drives me up a wall, especially if I am watching TV in the dark and cannot see the remote. It is black with dark buttons, so very difficult to navigate in the dark. I have had to memorize the feel of the remote for navigation of it and I still get it wrong!
The remote has to be pointed somewhat in the direction of the TV/Roku, so that is nice.
I was so happy with a Roku stick on my office TV that I purchased a second for my family room TV so my wife could enjoy it too. Works fine. I use my iPhone app to control both.
