Lenovo's ThinkPad Helix has had one of the rockier roads to the US market, having been promised for February only to be delayed to April. Things are getting smoother, however, as the first units of the are rolling off the production line -- and there are already customers waiting at Seton Hall University. Keeping up its recent practice of handing out gadgets to junior students, the school expects to test the dockable Windows 8 tablet within a few weeks, and then deliver about 2,000 units to newcomers starting in June. The turn toward a hybrid lets the university settle on one PC design for the fall rather than divide its attention between tablets and Ultrabooks, Seton Hall's Drew Holden says. As for the general public? Lenovo hasn't officially put the Helix on sale through its own store, but a handful of customers say they've already received theirs through other channels. In any event, keep a close watch on third-party stores if you're willing to part with $1,499 for a ThinkPad convertible.
