I am not a Pi hater. Seriously. The Pi's are just the only major device/device category I personally haven't owned/fixed. I respect a device that can play most 1080p and de-interlace. And refresh rate match, I hate going backward on that.

-Any other general advice/warnings?

Just a wee bit...
The Raspberry Pi's are pretty popular, especially outside the US so some detail on proper setup really is needed.

I have a pretty big media library on the RPi (3400 video files and growing) and these are the recommendations to get the best performance from it: (Plus anyone with ARM devices will benefit from some of these tips)

- don't use a local library, thats what cheap NAS storage is for.
- buy a 512MB RPI B+
- use Ethernet
- get a good microSDHC, the updated NOOBS Samsung one is recommended.
- Max Overclock it with a recommended 5V/2.0 Amp power supply that includes a decent thick USB power cord.
- use force_turbo=1 Overclocking. This is Max Overclocking all the time, not adjusted dynamically.
- DO NOT use local Metadata scraping as the write speed of most SD cards is slow plus the CPU just cannot handle parsing all that data. Instead use external Metadata scrapers. I find the very recently updated MediaElch excellent.
- Store all media in separate external folders which includes the associated metadata.
- for fast Kodi GUI and Media Library browsing use NFS and the above folder structure recommendation. NFS taxes the CPU very lightly compared to SMB. You want your fast Ethernet Network to do all the work, presenting the Pi with all that Metadata instead of taxing the CPU.
- Library Scanning speed used to be terribly slow, now its pretty quick using Openelec 5.0 / Kodi.
- Kodi > Settings > System > Video > File Lists > Extract thumbnails and video information > OFF
- Set the gpu_mem=256 in the config.txt file to play all Skins
- choose a low textured Skin for best GUI speed

- deinterlacing Live TV is pretty good too using: (thanks Popcornmix)
For DVD resolution the RPi will do a motion adaptive deinterlace similar to YADIF.
For higher resolutions (e.g. 1080i) it will do Bob. Both will optionally double framerate.

- the Youtube addon is a bit slow.

Skins: Aeon Nox works but it is not what you call snappy. The low textured graphics Skins work the best.
Confluence no problems at all, Maximinimalism, Conq. They are all snappy.

My personal favorite and one thats a bit different is the skin Eminence
