I notice that posrers are starting to compare their rmb to certain ultrabooks. I have discussed my Lenovo Yoga 3 Pro and my RMB. Oters have discussed theHP Spectra. So this would be a good place for anyone to bring up up NEW ultrabooks from the win10 world and how they compare to the poster's RMB. By the way I love my Y3P and it has much more gong for it than my base rmb. The Lenovo 900 has replaced it this year.
