Regarding the $99 Sony PS3 3D monitor..that's a good deal yes, but
there are couple of things, people should know if they indeed to use it either as a TV or PC monitor besides PS3 gaming
a) It DOES NOT have a TV Tuner - Inputs are: 2 HDMI or 1 Component input, 1 stereo and 1 head phone (ok for satellite or cablebox use but no ATSC cable or over-the-air tuner)
b) It is GLOSSY or GLARING, (not Matte finish), so make sure you have a dark room otherwise you can see a lot reflection especially movies with dark scenes.
c) No PC VGA (analog) or DVI input. So, PC must have HDMI or covert using DVI-HDMI or VGA-HDMI adapter or cable. Certain PC display adapter may not be able to display in clear 1920x1080 screen in crisp mode - it depends on your adapter.. the text could be fuzzy.
d) 3D glass - this is active shutter, must be charged up.. pretty expensive to replace - so be careful with them.
e) Yes, it is true 50/50 chance that they're defective (blank out, random shut off, color bleeding, etc after 1-2 weeks of normal use) - have to be replaced by Sony thru RMA. It's NO USE even with protection plan from Best Buy because they'll give another defective one to you out from the box. It won't fix the issue. Only the RMA ones will be fixed when you return it.
f) No remote included, the buttons are difficult to reach (facing the back).
You need to get the new PS3 bluetooth remote ($20-$25).
h) The audio is ok.. but kinda of soft in some movies.
Other than those above issues, I find the following nice things
1. It is a great monitor for PS3 gaming!
2. Beautiful 3D.. good for gaming and watching 3D movies
3. Great Simulview gaming (limited to some games) with a friend
4. Looks like a GIANT PSP box. Looks good in your room.
