I mostly love my 600. I like jotting down notes, looking up stuff in the dictionary, book marking pages. I like the size and weight. I can read the display just fine in most any environment I need to. I do have to struggle a bit when trying to read it in my radiology reading room, but c'mon, I'm a radiologist--that place is like a bat cave.
But, it does have appreciable screen fade in sunlight. I got a replacement refurb unit and it's better, but it still fades perceptibly and I'm worried it will get worse as the summer advances and we get more perpendicular to the sun's rays 'round here in Minnesota. It wouldn't be a deal killer if I knew that this was normal, and was told that it was normal before I bought the thing (like the reflection deal that bugs so many people, or the really crude music function). If I shade it during page turns it's fine; an annoyance to have to do that, just a minor one. But I've been assured by multiple folks on here that it is NOT normal, and have been majorly yanked around by Sony technical support/customer service.
So, I find myself irritated that Sony has my money and is getting away with passing off what by all accounts is a defective unit. Last time I was on the phone with them, they said is was "normal, the screen is protecting itself. You need to move into the shade." They did offer to take it back and refund my money when I told them "If that is the case, you are engaging in false advertising". But they wanted ME to pay shipping if I wanted my money back
. And I don't *want* my money back, I want a unit that is not defective.
I've been eying the iRex 800. Little bigger screen for PDF's, now it has annotation, a few other features that are reportedly better (holds zoom settings). If it was a comparable price to the 600, I'd tell Sony to take their unit and shove it, and get an iRex. But it's not, and I'm not sure if I'm over 150 bucks mad.
I'm leaning towards keeping it, but I tell you what, I don't know when I'll buy another Sony product.....
