I remember on the Archimedes using PC emulators, both Acorn's one (which was oriented more towards business applications) and Dave Lawrence's FasterPC (optimized for older DOS games using 320x200 256 colours). Both only emulated an 8086 (or 80186 in FasterPC's case), so they were good for Civilization or SimCity but not newer things. I mention them because, to squeeze decent performance out of an ARM running at speeds as slow as 8MHz, they were hand-written in optimized assembler. This was the older 'ARM26' instruction set where the program counter and flags were contained in a single 32-bit register, so the code would need modification to run on recent ARM processors; and in any case the I/O part of the code will be totally different. But that doesn't stop me wondering about the core CPU emulation and how fast it might go on modern hardware.

So Windows 8 doesn't have the Aero Snap, Aero Peek and other animated window management thingies? I can understand that Microsoft marketing stopped calling it "Aero", and that Aero Glass (the odd half-transparent effect on window borders) has been dropped, but I thought the thing itself (whatever it's now called) had been kept.

Sorry what? 'Light' and 'heavy' can be used as relative terms, just like big and small, hot and cold, or pretty much any adjective in English. If you say 'the lightest substance', it's quite clear that you are talking in relative terms. Also I think you are confusing 'substance' and 'object' - a single neutrino is not a substance, it is an object. Water is a substance; a drop of water is an object. I mentioned gravity to deflect any possible nitpick about 'heavy' being different depending on what gravity you measure it in - since we normally understand heaviness as the force of an object being pulled towards the ground, in other words as a measure of weight rather than mass.

It is normal to describe a material as light or heavy. These are shorthand for 'weighs less for a given volume' and 'weighs more for a given volume'. If you assume gravity is fixed - a reasonable assumption, since we all live on the same planet - this also implies 'less dense' and 'more dense'. What's the difficulty?

In fact there isn't a big issue with Windows XP compatibility and hi-dpi displays. I use a couple of 204dpi monitors at work and until recently ran Windows XP on the PC. Just set font size to 200% and pretty much everything works fine - there are the occasional things like installers which render with fixed pixel sizes and so have tiny text, but the applications you use every day don't suffer from that. Windows 7 is a bit better still.

I'm reasonably happy with Classic Shell, plus disabling Aero and other animated junk.

His original plan was to buy a bunch of cold medicine, Jesse warned him off of that. The next plan was to steal materials for making biker meth

Thx - I didn't know about any of those except Win-L to lock the screen. For my style of working (every window maximized on one monitor or another, no Aero or gadgets, file manipulation mostly from the command prompt) they are not that useful. But I can see why others might like them.

Yikes! How long is the warranty on Unicomp's keyboards?

When would you want to use the Windows key? Is Ctrl-Esc too difficult?

I agree that Apple's laptop keyboards are not very good but that's because laptops in general have crappy keyboards. I was reasonably impressed with the keys on the 13 inch unibody Macbook Pro (whereas the first generation Macbook Pros had lousy keyboards where the key tops would break off easily). Unless they have gotten worse with the new Retina models, I'd say the Apple laptops are among the least worst laptops for typing. What laptop keyboard do you like?

Does the Mac Mini have an external power brick? If so you could decide not to use the supplied power brick and power many Mac Minis from a single low-voltage supply. That would surely cut heat and power usage.

I use Windows at 200% scaling (both XP and 7) and it looks fine in pretty much every application; where are you seeing problems?
