Agreed - my parents and grandparents would love it. In fact once they get the shipping time down I think price isn't even that big of a deal to a lot of consumers. If my dad could put it in my grandma's living room next week he'd definitely pay $250.
The simplicity of my brother, sister, and me all being able to email our photos to one address and have them show up for our grandmother is what is really awesome about the Picwing.
AFAIK the samsung doesn't have that feature. I see it accepts RSS feeds so there are ways around that, but that's already getting too complicated.
Use it in conjunction with ourdoings and you could email your photos to an address that puts them all on the frame.
Edit: Your grandmother doesn't need to know anything about RSS if you configure the frame for her. She can just turn it on and off. Someday Picwing will give her an easy way to switch between feeds, but for now just set up one feed that you and your siblings send your photos to. (You can switch feeds on the Samsung, but it involves pressing a combination of buttons on the back.)
Your brother and sister don't have to be super technical either. You set up the site within http://ourdoings.com/ and create one email address. If you don't care about the web site distinguishing whose photos are whose, just give that email address to your brother and sister.
If you want to distinguish whose photos are whose, your brother and sister can go to the site you created, click the Edit tab, and "volunteer." After you approve them, they can go in and create their own email addresses, or upload by other methods, and photos will have your individual names associated with them.
Congrats to the picwing team for a great widget. It's really well done! They're a super talented team, and it's rare to get together people that can just really kick ass on both hardware and software.
Also, not all of those photos are mine, so I can't take 100% credit ;-)
It even pimps the YC logo.
Ah, the joys of not having a real job.
