Took about 10min. Very easy to do. Video covers everything. All I've done so far is install Gmail, Chrome and Moon+ reader. All appear to work fine.
This is done without "rooting" the device.
I feel much more comfortable putting Google Play Store on the device and then getting my apps from Google than the various other "link here to the apk" type solutions which MAY open you up to malware (not that Google Play is completely free of that risk).
