First off let me say I absolutely LOVE this device! Props to Onyx for being innovative enough to pack a full powerful Android tablet into an e-ink display of truly enormous (but also well sized) proportions. Everything from the screen size to the navigation feels well thought out and highly functional 
For me, I primarily use this device as a productivity device - reading and replying to email, messaging people on various messaging apps, proof- reading documents and spreadsheets, and browsing content in firefox - iām even typing this post on my Max 3!. This device has greatly reduced my eyestrain and the frequency of my headaches! 
Of course I use it reguarly for reading and note taking as well.
I greatly appreciate the inclusion of MS Word, OneNote, and Excel in the Boox App Store, which I use a very frequently. The one productivity piece that I think is still missing is MS Outlook. I would like to request that MS Outlook be included in the Boox App Store. Currently, Outlook from the Google Play Store takes a while to get mail and mostly, will only refresh well on Speed Mode.
Please consider adding this app to the store in the near future!
