The flush glass screen of the Note Plus really makes this feel like a premium device. I have the 13.3" Sony and was waiting on a flush screen from Onyx before I purchased a 10" device. Still optimizing it with my favorite/smooth apps, but so far I love it.
Also purchased a Lenovo Thinkpad tablet 2 Bluetooth keyboard:

They are a perfect fit for the Note+.
Only other experience with Onyx is that I previously had the N96 and I sent it back as it felt cheap and slow.
