Summary: Fan way too loud and system runs fairly hot. Not exactly my ideal combo system. I quickly went back to my X1 Carbon because of the quieter fan and approximately comparable weight. For the cost of the system, the Microsoft Surfaces are easily better alternatives. Sorry Lenovo.
Summary: The Helix definitely works. Great keyboard, nice slim computer, good materials... You pay for a premium computer. Here is the good and the bad: + I love the keyboard. Great! + small + solid + high resolution + the tablet hardware works fine - taking it off an on.
Summary: - Frequent requests for buying additional software (for PDF, backup's etc) - Spacebar key (left side ok, right side or center needed extra push) - The helix has two batteries: keyboard dock and tablet. The tablet one stopped being recognized by the OS after a week.
Summary: Positives: 1. The particular approach of building a Win8 tablet/laptop combo is great (but execution is terrible) 2. The claimed 10-hour total battery life (but real-life experience isn't that) 3. HD Screen (but, as a minor point, text is not easy to read sometimes) Negatives: 1.
Summary: The bad side: it's top-heavy (tips over easily), a little glitchy, freezes briefly as if it was still using a hard drive, periodic crashes when I pop screen from keyboard. Definitely need external monitor, keyboard and mouse with this for intensive use, so add that to the already high price.
