The screen doesn't really get foggie, though sometimes int he tub it does, but that's a HOT tub!
Also, I think they are the ones that suggested it, but you save those little silicon thingies from new shoes and med's and stuff and put those in there to keep the moisure down
There used to be a $50 model which was nice also, I had that one before. I only got this one through luck and then passed on my previous model to someone else. But the main advantage for me with this one, is being able to listen to my MP3's or audio ebooks while using the case to protect the Clie.
I agree with the cost thing, it's a lot but if you are going to use it, and it can go with different models as you change and upgrade, then it's like an insurance investment to me. I'll always have a PDA/Smartphone, so I invested about 2 yrs ago and still think it was a great idea!
