My brother is wanting to sell me his old iPad 3. He hardly used it so the battery is still good but it's an iPad 3 and I remember some complaining about its performance in iOS 7. Anyone know how well this works on 8.4 and so far how it runs on 9? My planned use is at work to stop taking my 12lbs laptop to meeting and use the iPad to take notes and show presentations on a projector. Probably no gaming or media usage. He is asking for $125, which seems to be an extremely good price.
