As said, the longer the throw, the less you see. I am at 2.1:1 and I still use a curved screen because I leave the A-Lens in place all the time. I decided that I wanted straight lines so curved my screen. I can run a PC desk top and not have any geometry issues that would otherwise plague a system with a flat screen.

Going from the W5000 to the Optoma has been a bit of a pain due to the lack of lens shift (although my Benq sh!t the bed and lens shift stopped working), but I've made due. I'd be interested to know if the Benq has the ability to stretch half SBS content. This is definitely something I'm going to look into.
Yeah I got the W5000 in 2008 and last year (just over 1500 hours) it got a case of the dreaded "vertical stripes". BenQ said they would fix it, but because it was out of warranty it would cost me just under $800 and they'd only give 28 days warranty on the new parts. I then got the chance to buy the W6000 at about half the original RRP with full warranty, so jumped on that. I would like to upgrade to the W7000 for 3D now as I am impressed with the W6000, and 3D would be just creme on the cake.

Well of course there are because the curved screen serves the purpose of correcting an issue caused by adding the A-Lens - that is pincushion.
When you remove the A-Lens, you have removed the very reason you curved the screen in the first place and the image now barrels. Some don't mind this as it is probably not as offensive as the pincushion the curve corrects.
In the end of the day, I don't want either pincushion or barrel and one reason why I leave the lens in place all the time. The other reasons are equal pixel density regardless of AR and only one calibration setting required is required. It also makes the system extremely easy to operate with a change in AR a simple push of a button.
