I've always held that power (features) trumps speed unless we're talking about OLTP. Machines will get faster quickly. Providing a strong platform is more important than being the fastest, today. YMMV.
Every new machine or processor is dragged down by the increased bloat and inefficient coding of the new OS to go with it. It'll be quicker starting up, only until you've installed a few basics, then it'll take as long as it always did.
They feel too slow always. Always have. Movies show things happening instantly - I now believe that will never happen. The Matrix should have included 1m "Loading" dialogues. :)
I get annoyed waiting for websites to load on multi Mbps broadband just like I did in the 90s with a dialup connection.
Sure things are doing more, but I'd like the cycle to include making that "instant" future please.
