Ditto. I cut the cord in late 1999 and don't see any reason to go back. I mainly like movies (all kinds: old/new, blockbuster/indie, etc.) and NetFlix (discs) fill that void better and cheaper than cable can.
NetFlix instant (streaming) is also nice, but the selection is much, much less interesting. Very few titles on NetFlix streaming aren't available on disc, but most of those on disc are not available streaming. Streaming is great, however, for watching a TV series (when available) because you don't have to wait for discs in the mail. It's also nice to get HD on some content that's only available on DVD (not Blu-ray), but NetFlix streaming (at least these days) is a single audio track and non-optional subsititles only if the audio is not English. DVDs and Blu-ray often provide options for audio and subtitles that are very nice to have, especially for foreign films.
I don't want or need a game console (Isn't that what a PC is for? ;) and the Roku box seems perfect for a "set-top" box. I have 2 (living room & bedroom) and am thinking about getting a 3rd for the TV in another bedroom. The Roku box works great with NetFlix streaming (which makes sense because Roku was spun off from NetFlix when they decided they weren't interested in selling hardware) but it's also great for Amazon Video-On-Demand (including free titles for Amazon Prime members), Pandora (free with no ads!) and various other channels. The high end (still less than $100!) Roku boxes even have USB ports to connect external storage for viewing local content (home movies, downloaded stuff, MP3s, etc.) but they aren't what I would call highly compatible with lots of media formats.
For all my home theater needs, a nice 1080P TV plus quality surround/amplifier/speakers plus Blu-ray player (backward compatible with DVD and CD, of course) plus a Roku connected to the Internet via WiFi meets my needs very, very well. Oh... and we occasionally watch OTA (over the air) broadcast TV for local news, NFL games or the rare sitcom that's interesting and not available via NetFlix.
