Summary: I've had the little Revo since May now. Out of the box it is a really neat little machine. It looks good with the rest of the AV equipment. It looks more like a blueray player than a computer which is good for those that do not want big equipment. I think it is a very neat piece of equipment. I also purchased a logitech wireless keyboard which we use the vast majority of the time. So, why the 3 stars you ask?
Summary: I got this as a HTPC primarily to play DivX and H.264 videos off the HD and streaming over the network (the blu-ray player was a nice touch, but I haven't really used it). It turned out to be noticeably choppy while playing back even 720P video connected to a 1080P display. This was using VLC as the player and the default install of Windows x64 Home Premium with all the latest drivers.
Summary: I had high hopes for this machine. The design is slim, sleek and kinda cool. It was up and running on my LCD wide screen within minutes with no hassles at all. That said, it does not have sufficient power for streaming media without issues. Streams from netflix, abc, fox and cbs are all occasionally choppy and the CPU is maxing out at 100%.
Summary: There no documents. Without it the keyboard is hard to figure out. I am still trying to figure out how to do a right-click. My suggestion is use your owe keyboard to do the setup/upgrade and connect the wireless network. The Acer software does not give an option to copy pictures from the SD-card. Why does hardware company like Sony/Dell/HP think that user want to use their POS software? It's nice that it came with HDMI cable.
