$25 a day to save 3 lbs, interesting view. I suppose, taking that into consideration, it would also be worth it over the long run (if we really get into backpacking)... hmph. Damn, why are tents so expensive.
EDIT: Btw, yeah we could set up this tent blindfolded, if we had to. We've set it and disassembled it so many times, we know it very well. For what that's worth... which is apparently a lot!
Although, in an Icelandic summer, there's no shortage of sunlight (even at 2am, it's nice and bright)... so not a huge issue.
