Reporters weren’t allowed in, and analysts were banned from taking photos, so we don’t have any images to show.
However, The Wall Street Journal has some first-person accounts from attendees that paint a fairly clear picture.
“The first one they showed us was the size of a [Galaxy] S3 smartphone, which can be folded in half from top to bottom,” Daiwa Securities analyst Jae Lee told The Wall Street Journal.
Another device was the “the size of a lengthy wallet, which can be unfolded on both sides into the size of a tablet computer,” Lee said, adding that both of the devices looked pretty good.
While the first sounds a little like a fancy clamshell phone, the second sounds like a really quite innovative blend of smartphone and tablet.
Samsung has said that it wants to formally unveil foldable phones by 2015, but the shift from glass screens to a bending plastic may take some time to arrive in retail. In the meantime, we have the curved Galaxy Round to tide us over.
