Which eReaders and tablets support multimedia and CSS3 features?

Vook has put together a list of some of the devices that support multimedia enhancements, along with the maximum eBook size on each device (which turns out to be dramatically affected by both the device and eRetailer), and a list of CSS elements that can be controlled in Vook's editor, with which devices they're supported on. Here's a summary:

• Only iOS devices running iBooks and the Kindle app, and the Nook Color and Nook tablet, support multimedia enhancements. The only desktop PC eReader that supports the enhancements is Vook's own Reader software. 
• Here are the maximum file sizes for various devices and eBookstores--conventional publishers (with "Vendor of Record" accounts) get far more file space than do self-publishers, which makes self-published multimedia-enabled eBooks impractical:
• Apple's iBookstore: 2GB 
• Barnes & Noble Pubit! (self-publishing): 20MB 
• Barnes & Noble via Vook distribution relationship: 600MB 
• Amazon Kindle Direct Publishing: 50MB 
• Amazon via Vook distribution relationship: 650MB
• The Vook source link has much more information, but in general: 
• iOS devices handle all the CSS3 attributes. 
• Nook devices (both eReaders and tablets) handle all the CSS3 attributes. 
• Kindle devices handle only a subset of the CSS3 attributes, with the Kindle Fire supporting a few more than Kindle eReaders. 

New York Magazine publishes first eBook through Byliner

According to the Nieman Journalism Lab, New York Magazine has published its first eBook, a compilation of columns and articles from the past five years as selected by readers through the nymag.com Most Popular Stories feature. They've partnered with Byliner, which does publish original work but is primarily a discovery engine for content from established writers on the web. The new eBook, "New York Magazine's Most Popular," will initially be sold through Apple's iBooks for $7.99, and through Amazon and Barnes & Noble shortly after. Revenues will be split evenly between New York Magazine and Byliner. Individual authors within the anthology will be paid a "courtesy fee," and Byliner will also sell individual articles, for which the authors will get a cut of revenues.
