The short answer is: Intel Mac: probably around Nov/Dec 2008 PowerPC Mac: unknown (probably never) Linux: probably mid-2009 Xbox360: November 19 PS3: unknown (maybe never) Stand alone set-top box players: On May 20th, the Netflix Player by Roku was released for $100, more expected in Fall 2008.
They are testing Intel Mac support via Silverlight 2 with a few people right now and it should be available to everyone by the end of the year. In the meantime, there is a workaround for Intel Macs by installing Boot Camp, Parallels, and Windows. There is a similar workaround for Linux.
As far as I know, Netflix has nothing planned that will allow them to support PowerPC Macs.
On April 21st, Reed Hastings (Netflix CEO) said that they have deals with 4 companies to produce hardware for Instant Watching. LG was previously announced to be one of the 4.
On May 20th, the Netflix Player by Roku was released for $100, more expected in Fall 2008.
I use virtualbox with xp installed. Virtualbox is the free solution to vmware and parallels, that in my opinion is way better then both paid programs. I have used them both and vbox offers more features, minus image mounting if you have a bootcamp drive. Hopefully that will be fixed soon. That's the solution for my macbook pro.
I have a shiny MacBook Pro (2.33GHz Intel Core 2 Duo...) and all i needed for instant watching was Parallels and Boot Camp.
The Windows window opens, i have IE in there, and i watch tons.
Remember: it's not the Mac. It's the OS. If you'd like more info on the particular set up, let me know.
our work to get instant watching to the TV will be more and more available in 2008 (aside from cabling up laptops to TVs... which of course can be done, but isn't for everyone)
