Not really. My Lenovo Y700 tablet is 375g, and my Kobo Aura One is 230g
The Y700 has a bigger screen and is 100x better at everything though.

It's also _extremely_ better at everything, including for reading books, so the higher weight and (2x, not 3x) cost are well worth it.
The Kobo battery doesn't even last that long with the backlight and wifi on, and at least mine wipes its storage and OS when the battery runs down completely. The screen and UI are also the worst thing imaginable. Using eink devices is basically equivalent to torture.
You also miss the point, that limited functionality of readers is feature not bug. It massively reduces impulse to start browsing youtube etc.
All together, price, weight, battery time and limited functionality is what makes the whole proposition attractive. I personaly do not need yet another androd tab even for free.
Personally I'm not overly distracted by android apps when I'm reading a good book, but YMMV.
My Kobo doesn't have any buttons.
It also forces me to go on wifi and make a Kobo account to use the device at all (even if I'm just interested in copying epubs).
In short and honestly after 5 years of ownership: fuck Kobo and and fuck ereaders in general.
