#1. Console games (XBox 360, Playstation, Nintendo - not just XBox - and I say that because I see a lot of projector ratings that only use the XBox for games, and the Nintendo consoles have a lot of games with far brighter, more saturated colors for example)
DLP & LCD will both deliver for you. The Sanyo Z4 is a good deal sharper than the AE900 is, but also delivers less light. At a 100"-110" diagonal, you are better served with a brighter projector. The AE900 is good, but DLP will almost always deliver far more light (25%+ more!) after proper home theater calibration. This can really give the hightlights some real punch to them. If I had the budget (I didn't when I bought) then DLP would be the way to go. With current pricing putting DLP much closer to LCD, I would shoot to get a DLP projector instead of LCD for the better true contrast ratio. The downsides of DLP models has been discussed above, but if you are doing your room from scratch then this likely isn't going to be an issue for you.

#2. PC games & PC applications
PCs + projectors: Let's be very specific here. Almost always, when a PC looks bad on screen it is because the PC is not setup correctly. For best results you absolutely MUST match the output resolution of the PC to the native resolution of the projector. So, a projector like the InFocus IN76 which is 1280x720 resolution really should be fed 1280x720 from your PC. If this is a bit much for you to deal with, or games only like 1024x768 resolution, then perhaps a 15:9 projector, like the Optoma EP1690 will serve you better.

There are several models that use 1280x768 DLP chips and they kind of give you that happy medium between home theater applications which are 16:9 and PC applications which are easily established at 1024x768. A very personal decision for YOU to make on this one - but at least you have options.

Movies are, IMO, one of the most forgiving things with projectors. Because there tends to be a lot of movement, and because you can get such excellent DVD players these days, almost any projector you buy that is designed for home theater usage will do a very good job. Once you have the 'decent' home theater projector - you will have good movies on it as long as the DVD player you use doesn't stink.

One non-negotiable for me is the display of text. I can't handle fuzzy or jaggy text, but I haven't really come across any articles that contrast DLP vs. LCD as far as text display goes.
Text is kind of covered above - but let's focus on it a bit more. Text is a function of what resolution the material you are sending to the projector is. With a PC, if you match the resolution of the PC to the projector, then the text will be pixel-for-pixel accurate and look perfect on screen. Video games are a different story though. The video that is output from a video game is often blurry from the start. It often has some aliasing and imperfections that will hinder the quality. PS2 is not going to ever deliver the way an X360 will or the upcoming PS3 will since the technology is over half a decade old and it was designed for connectivity to a standard 480i television. Likewise, subtitles on DVDs may not appear perfect. But, a better DVD player will do a better job with this and good upconversion can match text for subtitles far better than cheap DVD players.
A good screen, as mentioned, can be a big plus, but in my experience, something like the Carada Critereon screen w/Brilliant White material can do a phenomenal job in a theater black environment and is my goto screen 90% of the time.
