If you were biding your time until late February to pick up a ThinkPad Helix, we've got some bad news: Lenovo's revealed on Facebook that the convertible Ultrabook has been pushed back to a March or April release. For a refresher, the Helix packs an 11.6-inch 1080p Gorilla Glass display and carries a $1,499 price tag in its base configuration. Mum's the word on what's forced the flexible hardware closer to spring, but we've reached out to Lenovo for confirmation and more details. [Thanks, D]Filed under:
