I like that machine specs and form factor (the "gaming" style is tacky, but I know that is not the point here ): my current machine is a quad core laptop, albeit an older 3rd generation i7 quadcore.
The direct competitor from Dell would be the Inspiron 7000 "Gaming" series ( again, let's skip the gaming style).
http://www.dell.com/it/p/inspiron-15-7567-laptop/pd?ref=PD_OC, and that is basically the same as the Dell Inspiron 7000 Gaming series
The asking price is €1000 for the base model (basically very comparable to Y700 you showed; all these prices also include 22% VAT); to upgrade RAM, memory (FDD+SSD), graphic card and processor they add €200: decent deal if you ask me: I would go for it, stretching my budget); for more €279 more, there is also a top of the line UHD version that also goes full SSD... Not as much value for money in this upgrade (for my use, at least) and definitely more into high price territory.
Now, if the touch panel and the 360 hinges can be had for €200 then I am happy, as I said.
However, what I see is that DELL is indeed offering an Inspiron 2in1 with 360 hinges and touchscreen: it costs €1100 Euro for the 16Gb+512 SSD version! http://www.dell.com/it/p/inspiron-15-7567-laptop/pd?ref=PD_OC But this 2in1 Inspiron it comes with substantial downgrades: it is not quad-core (i7-u), gone is the dGPU (integrated graphic card), there are less ports, the battery is dwarfed (that machine has less battery then the Eve-V, ridiculous! ), the number keypad is gone...
So... very roughly:
(quad-core upgrade) + (dedicated 4gb card) + (1.75x larger double the battery) + (full keyboard & ports)
- (360 hinge + touchscreen) = € 100
This example (and similar ones) is the reason why I still doubt that (360° hinge + touchscreen) is a $200 item you just add to a compelling laptop.
I'll say it one time again: if it is possible, I would be happy and tempted!
However, if it isn't, and the option are either a) + $400/500 for the 360 hinged tablet mode on top of a $1100-$1200 machine or b) said machine at $1100-$1200, without hinge upgrade... I think I'd be very tempted to choose b) and keep that extra money (and buy 2/3 of an Eve-V m3 !!!).
