THEY ARE MORE POWERFUL
- who cares?
Seriously. If we only cared about raw CPU power, why do we care about Amigas at all? Because they have some charm that other computers don't. x86 has performance, but it has no charm. Ask yourself which you would rather go for dinner with.
Besides, hulking great desktop PCs with beastly CPUs are becoming something of a niche market these days. Most people seem to prefer the convenience of laptops and tablets, and if they want games too they get an Xbox. Only hardcore gamers need the performance of their x86-based PCs.
ARM is taking over, get used to it. x86 is the past of computing, not the future, and ARM will catch up with x86 performance before too long as well. Microsoft went to the effort of making Windows 8 work on ARM for good reason, they know the change is coming.
