The Topjoy Butterfly was a Kickstarter campaign for building a tablet using a new screen technology called DES Slurry, which boasts more colours than currently available colour e-ink screens.
I was not a backer for this device (too many warning signs) and so haven’t had any hands-on experience with the device (and it is unlikely I ever will). However, a few eWritable readers did back the campaign and kept me updated with the story.
Unfortunately, there were several issues with the campaign, including long delays, poor communication from Topjoy, and when the device was finally shipped, not everyone got their tablet.
Those that did receive their tablet reported that although the screen did display a lot of colours adequately, there were several issues including ghosting, sluggishness and permanent ‘staining’ on the screen.
This tallies with what has been published online by other Topjoy Butterfly backers.
So, I cannot recommend the Topjoy Butterfly at this time for anyone that plans to use it as a productivity device. The only subset of users that might find this useful are those that have a technical curiosity about DES Slurry technology and want to see it in action first-hand for themselves.
