It's been almost a year since OnLive first There have been some concerns regarding the service's quality but the company is promising a fluid and lag-free experience -- clearly they have a lot to live up to. Standard-definition games will reportedly require a 1.5Mb/s connection, while 1080p high-definition gaming at 60 frames should be available sometime in 2011 and will require 5Mb/s. OnLive will initially be available on Windows and Mac OS X systems through a small browser plug-in, with a MicroConsole that can be attached directly to HDTVs arriving later this year.
