A neat little package arrived yesterday, Chromecast was on my doorstep. The instructions for setup were very simple, though I originally thought the USB charger was optional. It does not work without that USB being plugged in, so be warned. Luckily I did have a USB port on my tv and didn't have to mess with the power strip buried in the back of my entertainment center. Setup took all of 5 minutes, mostly finding out that the chromecast doesn't work with my 5G wifi, only the slower connection. It could be my TV or the chromecast, who knows without me delving into the forums. If you want decent sound, turn up TV volume PRIOR to casting. For some reason, this was the only way to get volume control, as my remote failed to work for me after I started casting. Netflix experienced a lot of lag, weird since I have great Internet and no trouble with iPad, surface or android tablets while streaming from that service. YouTube was better, but not by much. Thank goodness I can get Netflix through Xbox. I assume the limited amount of castability options will change, as more services integrate. I do not have Apple TV, so I can only compare to Xbox at tis point. Xbox is a pain, so running chromecast from the iPad or laptop was so much easier, just wish the streaming was better. You absolutely can use other tabs and strema at the smae time, so that functionality is what they promised. I am going to try it out in a classroom this week and update this review. Since I know I have strong Internet at home, I have no allusions that the streaming will be faster in a school, but there is always hope. I also know that any new product has bugs that will be fixed. For the price, if it works it will be great value. I also saw online chatter that I may be able to get netflix free for three months with the chromecast, so I will be checking into that. I will update as I get information.
