Depends in my eyes - matter of fact is that we've put pretty much the best components we currently could get for a reasonable price.
And even if you're Lenovo, you can't really upgrade your device every half year since once you've reached a certain point it's gonna be hard to upgrade. If you're e.g. at the SP4 level, what would you want to upgrade every year?
I feel the reason they can improve their lineup every half year is because their lineup has so many points they can improve on.
And while I'm not sure we can hold the title "best 2in1" for 2 years, but I feel that at least for 2017 the V is gonna be the device to beat - because pretty much what could you do to improve the V? I personally feel it's gonna be hard to improve the V - and I feel that when the community wants a new 2in1 the V2 will have a hard time beating the V.
