You don’t need to spend more than about $200 to get a powerful Android tablet that will last years. Because they have microSD slots, you can easily store pictures and apps to the SD card if the internal storage is too small. I don’t recommend the sub-$100 tablets in general due to poor display resolution and slow CPUs.
I only list tablets in the $200 range that support Android 7 / LineageOS 14 (and the Nook for reference). Click on the tablet name to see benchmarks.
|Tablet||display size [inches]||resolution [pixels]||RAM [GB]||SSD [GB]|
|Nvidia Shield K1||8||1920 x 1200||2||16|
|Asus Zenpad S 8.0||8||2048 x 1536||2||32|
|BN Nook HD+ Ovation||9||1920 x 1280||1||16|
Nvidia Shield Tablet K1 Android 7 Nougat, $200
The Nvidia Shield Tablet family is on Android 7 Nougat with reasonably up to date security patches. The CPU and CPU are more than powerful enough for the games I have tried on it. Dual-window capability of Android 7 Nougat is a killer feature, especially suited to the large tablet screen. Watch YouTube while answering email, browsing the web, or just about any other dual-window combination on Android 7 Nougat.
When used in the home/home office intermittently, the battery lasts a few days between recharges. If 6-hour idle auto power-off is used, a few weeks of battery life are typical.
Wifi performance is excellent, no issues with crashing or overheating.
The 8 inch, 1920x1200 pixel display is vibrant and adapts well to ambient lighting.
The Nvidia Shield Tablet camera provides RAW output as well as the standard JPG.
Lineage OS on Asus Zenpad S 8 tablet
The Zenpad currently comes with Android 6, and Lineage OS 14.1 (based on Android 7) is currently available for the Zenpad.
The Zenpad S 8 has a rather weak CPU and GPU. The benchmark performance falls far short (worse) than the Nvidia Shield K1 Tablet. Thus, I would strongly recommend the Nvidia Shield Tablet K1 over the Zenpad, unless Lineage OS is an overriding concern.
BN Nook HD+ no longer recommended
With the recent changeover from CyanogenMod to Lineage OS, BN Nook HD+ is not yet covered. Since the last CyanogenMod Ovation update was from August 2016, despite the security enhancements of CyanogenMod, there is increased risk of the Nook being hacked. This has led me to discontinue recommending the Nook HD+ for a second tablet, kids tablet or travel tablet. Although the Nook is on the LineageOS supported list, this means they may eventually support it. Unofficial builds of CM12 for Nook are on the XDA forums, but are no longer updated.
Another reason I’ve left the Nook HD+ behind is that while the CPU was fast enough to handle streaming TV at SD (HD experienced dropouts due to CPU load), and YouTube in HD, the growing popularity of streaming YouTube Live and Periscope are beyond the Nook HD+ CPU capability. YouTube Live viewing on the Nook HD+ drops out every several seconds. Periscope viewing experiences even more severe dropouts.
