Earlier I was looking for recommendations here and now I have narrowed down my choices to IdeaPad 730s( i7, 16gb, 256gb, $790) and Thinkpad x1 yoga 4th gen (i5, 8gb, 256gb, $1142). Cost is not an issue. But what I'm wondering is Thinkpad worth the extra cost. I'm basically looking for solid build, light weight, good battery, display, keyboard and speakers
