Before considering this tablet, look at what real owners (not paid reviewers) have to say about this shoddy product and disenfranchising manufacturer. In over 30 years in the IT world I have never seen such a vast group of customers so abused and orphaned by Dell.
My wife bought me the Dell Venue 11 Pro 128GB i5 7139, the stylus and the battery/keyboard unit for Christmas of last year! It arrived January 16th the following year.
Six months of fixes, patches, numerous BIOS flashes, motherboard replacement, power supply replacement, stylus replacement and countless emails, chat sessions and phone calls later, we are without any equipment (all received by Dell May 5th) AND they unilaterally closed our case file without refunding us for the tablet.
As of this morning's phone call, we were told Dell "reset" a new case file (which reset their required response time) and that they are once again looking into it; that we should hear from them sometime in early June. This shoddy design and support of this equipment is only surpassed by their return/refund groups.
