Well... I've got nowhere to move, except only back in time :) All laptop manufacturers stopped using high-quality LCD panels and switched to selling overpriced TN-film based junk (often glossy, to compensate for lack of deep blacks). Some of these machines cost a fortune (like my MBP and ThinkPad) while they're capable of only 262K colors instead of used to be standard 16.7 million, and don't get me started on vertic…

All laptop manufacturers stopped using high-quality LCD panels and switched to selling overpriced TN-film based junk It seems so: http://www.robgalbraith.com/bins/multi_page.asp?cid=7-9320-9... We know of no IPS screens in current-model laptops, ThinkPads or otherwise, and it's a shame, because our T60's FlexView display has some killer attributes. But that is a technology-based comparison, rather than a performance-…

there is a reason OHV engines can't perform OHC engines, mass. With OHV engines you need pushrods, which add mass to the valve train, these aren't needed in OHC engines. Generally to get more performance out of a given displacement engine, rpms are increased. When rpms are increased with OHV engines, you run into problems controlling the valves because you have a much larger mechanical system, which requires larger springs, pushrods also flex. All of this ends up mattering in a big way. F1 engines have overhead cams for specifically this reason.

F1 has displacement limits. http://en.wikipedia.org/wiki/Formula_One_regulations#Engine

F1 is not relevant to the world outside racing, where there are no displacement limits. Important engine metrics in the consumer world are size, weight, reliability, repairability, fuel economy, and capex economy.

But the RAM is now harder to change than previous model. I guess one changes HDD more often than RAM, so this is sort of an improvement, but...

How often do you change RAM? More than once or twice ever?

Even once is enough for this to be a bother.

The question, then, becomes if you gain more than you lose.

I get pissed off every time I open my last-gen MacBook Pro, because I don't like the button. This is an anal mindset. I don't like the plastic outline of the computer, or the buttons and lines that I think shouldn't be there. It affects me a lot. So for me, sacrificing something that means I'll be annoyed one time for a device that's superbly beautiful is wholly worth it.
