What everyone should do:
1. Get a plasma, as big as you can afford. Don't go for "smart" features, go for size. buy samsung.
2. Buy a PC to use as your media centre. Sure it's not as compact but you can fit a lot of drives in and upgrade as you want with any 3D Card/CPU/etc. (Don't buy a HP PL MS).
3. Add your drives, and install XBMC. Hide PC in you wall unit or stand cupboard. Put IR-remote dongle on the outside. (Now you've got something even smaller than an Apple TV on the outside)
Why Plasma?
- Your SD content will look better, and full HD stuff, you won't notice a difference unless you 2cm away from the screen.
- Glass is easier to clean than LCD, which do get dirty and LCD can indeed get scratches easily.
- Deeper blacks.
- Don't worry about Full-HD, or LCD, or LED even, go Plasma. forget about "smart features" as your XBMC will be doing that job a lot better. this saves you money to get the bigger screen.
Why a PC?
- Lots of storage space. Sure 1080p will work via network cable/wifi, but it's just better to have it on the device itself.
- Use the PC as your media storage unit. now you don't need an expensive mobo that can handle 8 drives as you can have 4 in that PC and 4 in your own PC.
- You can add SB/CP/SAB onto it, to download stuff - not all "prebuilt streamer/media boxes" can do this. Connect via cable/wifi so everything is accessible on your Home PC as well.
- a PC is cheap. prebuilt media boxes that can run XBMC is usually expensive, and have maybe 1 HDD slot. cheaper devices won't run XBMC and you're stuck with a crappy GUI and limited firmware upgrades.
Hope this helps someone out there.
