The current iPhone SE is basically using as much of the old iPhone 8 (I think it's that one) as possible lol, the cheapest macbook pro is using 2 year old cpu's but most Apple users will lap it up anyway lol. I will say I do wish more companies would do a 'smaller' mobile phone (without the bezels ideally) like apple is with the SE though....
Hopefully the global climate will cause Nvidia prices to need to come down but somehow I just don't see it happening... this is nvidia we're talking about after all.
