The equivalent to a decend (brand named) Android tab is a Surface/3. Even that has quite a bit more computational power than a high end ARM unit while achieving similar endurance. Same for the high(er) end BayTrail units from Lenovo (TPT10) if you prefer Wacom over NTrig. With the stylus the whole set of MS Applications is useable within the limits of memory and the CPU.
If you are living in an "MS centric" world with AD based networks and Exchange/Outlook/Sharepoint or Office set - the 10'' Windows unit with inductive stylus is a better choice than any 10 or 12'' ARM unit due to ease of integration (It's "just another Win/x86 PC after all)
