After reading the first post and all the rest , all good viewpoints and suggestions. I'll throw my viewpoint into the mix.
First of all, I thought I would be using the viewsonic pro8200 for everything, TV, gaming, movies , but it didn't end up that way. I mostly use my hdtv 42 inch TV for everything and use the PJ for special gaming, movies, sports. You saying you want your first PJ to do everything all the time, I don't think most of the rest of us do, I don't.
My 42inch hdtv is on all the time for either PC, 360 gaming, tv stuff, so that's how I do it.
Now as to portability vs stationary PJ. I did pick the viewsonic pro8200 because it was a cross-over PJ meaning it could be home theater and go anywhere PJ (school, business, travel). And I'm glad I didn't get the epson 8350 because it's big and heavy and doesn't have internal speakers, but that's me, others only want dedicated home PJ. If you are like me and have friends or family or would like to take your PJ on the porch at night or move to bedroom/den/ etc ... then think portable or cross-over like the viewsonic pro8200.
Other reasons some people are avoiding the epson 8350 at this point is bulb problems (it's something that epson is working on and is trying how to get the bulbs to work for longer periods of time, generally 400-700 hours bulb life with some reports 1,000 hours). Epson changed company that makes the bulb to see if that will fix problem, but it could be PJ design itself not cooling down the bulb the right way, so everybody that owns it hopes it's just the old bulb company that first made the bulb for epson. Also, epson is good for 2 years in replacing bulbs for FREE, if they didn't do that, you would be hearing MORE LOUD pissed off comments about bulb pop, especially at 300 dollars per bulb replacement, but after 2 years , you are on your own.
Also, some people swear by lens shift , but for me since I'm more portable I don't have a problem moving the PJ around room until it's centered and then it's done. The lens shift guys want the PJ in one location fixed and are not interested in moving the PJ around but using lens shift to make it work in favorite spot. So, all the lens shift guys picked the epson 8350 since most other PJ's don't have lens shift. I look for other things like cheap bulb replacement costs, longer warranty, read about if PJ as user problems before I buy, brightness, hdmi, 1080p, etc. So you have to look at the big picture (pun not intended until after I wrote that). Good luck, maybe PJ would be good everything always on solution for you and lens shift would be good feature for you , it's good you are posting about it before you buy, have fun and let us know what you get and how you like it.
