Well......I like MCE!
On the road on my laptop or my wife's laptop, we use it with an 8 dollar remote (Cyberlink) we found at a computer show to watch DVDs or listen to our MP3s.
Better yet, I set up a server with 800+ GB worth of videos recorded from TV, along with our all our MP3s, and pictures (used my 6 year old Dell Dimension desktop). Not only can our laptops access all of that content through the interface (so basically it can function as a 17" widescreen remote controlled TV with recorded content in any room), but my HTPC that's connected to my big screen TV in my living room can do that as well. As well as record shows like a TiVo, plus FM radio, plus MP3s, DVDs, videos, pictures (instant slide show for guests...10 month old baby, go figure), weather (free plug in), streaming radio (free plug in). All from the comfort of my couch, with a remote. It's so easy, my parents (over 60) could do it.
And it keeps surprising me with how easy it is. Example, when I built the HTPC, I bought a card reader to install in one of the bays. Afterwords, while my wife was watching TV (through MCE) when I put an SD card in with some pics, MCE came up with a dialog box within the interface saying "View Pictures?". Using the remote, we could instantly see the pics that were on the card, and even crop, rotate and fix red eye...all using the remote with just the Arrow, OK, and Info keys! I kept looking for the Apple Computer symbol somewhere, because it's been so easy to use.
My downstairs setup used to include an AM/FM amp/receiver, VCR, DVD, CD player plus TV. Thanks to MCE and a HTPC, it's now only the VCR, HTPC, TV, and amp. Once I finish digitizing the rest of my VHS tapes (the VCR routes through the HTPC) and get a better sound card (I used a lot of old parts to initially build the HTPC), it'll only be the HTPC and TV. One interface to control everything...
I think that's worth 16 GB.
