So I was around my cousins house today where he was showing me his new iMac. It's a 21" quad core i5, brought new from the Apple Store approx 2 weeks ago. As he was showing me some apps he had downloaded, he asked me whether it was worth him buying Lion or not. Confused, I checked his OS and found that it was running 10.6.8. Erm, so what's the best way for him to proceed? Will Apple offer him a free upgrade to Lion? Is it best to call in or lug the whole machine down to his nearest Apple Store?
