Looks great, but you don't own your place do you? Are you willing to buy a house or apartment based upon whether it can accommodate your home theater system?
I don't have any plans to buy within the next few years because i want to move out of the country in a couple years and I don't want the tax man up ******. But yes, it will always be a consideration for me whether buying or renting (my other big consideration is gas). It's not as difficult to accommodate a projector as you might think though, as long as you are willing to keep one wall empty (this is where WAF comes in for those that have them). Most home theater projectors use a short throw lens, so even if you don't have a big room, you can still project a big image. They also have lens shift, so you don't have to place your projector perfectly center with your screen (either horizontally or vertically). You can ceiling mount it, wall mount it, shelf mount it, or have a platform drop down from the ceiling (if you own your place). You don't even have to put a screen up, but if you do, you could use a cheap pull-down or more expensive motorized screen, hidden behind a valence. And if you use a drop-down of any type, you can have a wall-mounted plasma/lcd for daytime viewing in the same place. On the audio side, I favor concrete buildings or solidly built older buildings. I watch mainly at night and I use the system at a volume level that provides an impact. I don't want to deal with complaints. I'll also always prefer an apartment designed in such a way that I can position speakers away from the walls and corners, and where I can put my seating more in the middle of the room rather than right against the wall, so that my speakers will be at the correct angles for a proper surround sound experience.
