Appalling slowness, crashing rehearsals ... and so on of the best. I ask to have the fluidity of an iPad or Galaxy Tab 10 "but a minimum and there, clearly, nothing is with go. We had bought for our 4 year old daughter who does with not much we spend more time to unlock / reboot the tablet to be used in a minimum of good conditions.
Result: it takes the dust at the bottom of her wardrobe, it's time to spring another but soon blasé about its slow implementation.
Go your way, do not waste time tearing your hair especially if you're bald, you risk falling into severe depression !!!
