I've had a Spectre Folio (i7 8GB 1080p WWAN model) for the past 2 weeks, and I've thoroughly enjoyed it.
The review does cover all the positives but does miss out the 'feel' of the PC a little. It feels refined, capable and the long battery life and flexible modes, without obvious drawbacks such as poor lapability of the Surface Pro 6.
Is it perfect - not at all! It's considerably heavier than other comparable 2-in-1s; the performance is very acceptable for most productivity, but not for gamers; the pen loop is low-tech (stuck on the rear of the display) and the pen often gets in the way of my unfolding the device. The 1080p display is obviously not as sharp the 4K display (although it's perfectly adequate and the extra battery life is more useful).
That said, as an overall package, it's very good. If you're looking for devices to compare it with, I'd suggest the new 2018 MacBook Air - it has similar performance, added LTE, better battery life, a touchscreen and a pen included for an extra $100.
