For a few dollars more you get a 11.6" screen and detachable keyboard, and it is at your local WalMart: https://www.walmart.com/ip/47055697?wmlspartner=wlpa&adid=22222222227034893436&wl0=&wl1=...
You can attach the keyboard if needed. I have one of these and it runs SmartSDR just fine.
I have SSDR, MMTTY,and DAX running on it right now and they total about 25% CPU utilization with one slice. Takes about 50% total for four slices
