iPad mini or Thinkpad 8 : Convince me

Hi everybody,

I'm in the market for a new tablet, and have been coming back and forth between iOS and Windows 8.

After a month of deliberations, I've narrowed it down to two choices : iPad mini with retina display or Lenovo ThinkPad 8.

But I can't seem to make up my mind. So which one you recommend, and why ?

Keep in mind that I will be using the tablet for a variety of activities : TV show/youtube watching, PDF/book reading, rss reading, web browsing, note taking, etc. ; but no gaming however.

And also note that I don't really have a preference or attachment to a specific ecosystem : I own both a PC and iPhone, and I've owned and enjoyed equally both an iPad 2 and Surface RT.

Thanks in advance everybody :)
