I got the 47LM6700 a couple of days ago at Fry's for $999. Good deal I think.
I'm not a crazy techie, but here are my amateur thoughts..
1.The passive 3d is really awesome. way better than I expected.
2. There is color/edge burn that's noticable when I turn on the TV, but it seems to go away and not be an issue when I'm watching just about anything. It's a slight greenish color. Seems rather amateurish to ship such a nice TV with that glow, but it's not nearly bad enough to where I'd return the TV
3. The picture really is fantastic and the "professional picture setup" tool or whatever its called was nice to go through.
4. Here's a really annoying but fixable issue. The USB ports on the back ONLY support NTFS and FAT32 files systems. That sucks if you're a mac user like me. If you plan on playing movies, you're stuck using NTFS (FAT32 has a max file size of 4gb.) If you have a Mac, like most of us, you're USB HDD or USB stick is likely formatted for Mac, furthermore Mac's do NOT natively support writing to NTFS devices. I tried several workarounds until I found the solution. There is a program you can buy (free 15 day trial to make sure it works) called Tuxera NTFS. Download/install this and it will allow you to reformat your USB stick drive (using Disk Utility) as NTFS-Tuxera. Now using your mac, you can transfer files onto the stick, and the TV will play it just fine (I just tested it on an 7gb .mkv file). Btw, I tried several freeware mac-ntfs solutions and none of them worked (I'm using Mac 10.7x btw).
5. The Built in Youtube really sucks. There is a major sync issue between the audio and video. Also, the youtube app froze up and forced me to restart the TV several times.
6. The remote / nintendo Wii knock-off is OK. I think most people will want to get a new remote, but it's not that bad. Not that good either.
7. Did I mention the TV looks really awesome? Both aesthetically and the picture itself are gorgeous.
8. The 3d glasses are actually really comfortable and very light. You could easily watch back to back to back 3d movies with these babies before you'd get tired of having the glasses on.
9. Despite the issues listed above, I'm genuinely happy with the TV. I do hope they update the software and firmware, but those issues are quite minor compared to how much I enjoy the parts that really matter.
