Battery, RAM, and HD access on new 17-inch Macbook Pro

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 vertical viewing angles. [I'm a photography nut]

My latest Thinkpad took away true-color screen, the one before it took away standard display ratio, now the newest MBP said 'good bye' to the matte screen, frankly I'm not looking forward for the new announcements. Instead, I'm hunting for older Thinkpad T60s on ebay, the ones with standard ratio true color displays.

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-based comparison. There are no intrinsic reasons OHV engines can't outperform OHC (overhead cam) engines; spray-on fireproofing can't outperform concrete fireproofing; or TN panels can't outperform IPS/PVA/MVA.

Have you looked at the (TN-paneled) ThinkPad W700? http://www.robgalbraith.com/bins/multi_page.asp?cid=7-9320-9...

If you yearn for a laptop display that rises above acceptable, one whose colour accuracy matches a good desktop display, there's only one in this test: the ThinkPad W700. In fact, for us, it could just about replace a desktop display for colour critical work and even soft proofing for print in Photoshop

AFAIK TN-based displays are 6-bits per color, i.e. (2^6)x3 total output, not sure if that's a limitation of TN technology or just an unfortunate tradition.

But that is a technology-based comparison, rather than a performance-based comparison. There are no intrinsic reasons

I clearly see an abrupt color cut-offs in smooth skin gradations when working in Photoshop unless my head is positioned perfectly [speaking of MBP, arguably the best TN-based laptop LCD]. So... intrinsic reasons or not, I haven't seen a usable TN-based display yet.

W700 costs almost 3 grand. For that kind of money I don't need yet another "best TN laptop display", something like my 6-year old 17" Samsung with a true 8bit panel will do.

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.
