In Windows it works better if you stick to an exact multiple of 100%. In other words your choices are 100% or 200%.

Why on earth would you choose to base your product (something that presumably companies will use for many, many years) on something that will have no security support in just 4 months?

You wouldn't. You based it on something that would be supported for several years when you made the decision back in 2006. It's just that schedules being as they are, it has taken that long to develop the product and get it to market.

In the land of dinosaurs, where Big Companies do Stupid Things, it is fairly common for new products to be launched and then the whole platform end-of-lifed soon after. It's nobody's fault in particular, just how decisions get made.

If you have an Intel server running Linux is that really any different from a SPARC server running Linux or Solaris?

There should be some way to sell computing power to cloud customers. Like a live-CD Linux distribution you boot, and it connects to some online exchange to see if anyone wants to rent virtual machines. If nobody is offering enough cash to cover your power costs then it sends the machine to sleep. However, CPU power efficiency improves fast enough that even if the hardware is free and sitting idle in your garage, you still might not be competitive with specialist cloud providers. (Then there are the inevitable issues about data privacy, reliability etc.)

Panasonic's Toughbook rugged laptops have colour transflective displays. But the colours start looking washed out in bright sunlight, so perhaps the transflective part is black and white only somehow. And the readability in direct sunlight is not quite what the marketing wants you to believe - you're still better off finding some shade.

Yeah I'm just talking about the aspect ratio and resolution. Another good example would be the 'retina' Macbook Pros - they are also 16:10 though not quite such a high number of pixels (the 15" has 3/4 as many pixels on both axes as the T221). But since you mention it, I wouldn't agree that a slow refresh rate or poor colour gamut rules out 99% of uses. Probably only about 5% of users require colour accuracy; the T221 is no worse than most monitors, photos look pretty good on it. (I use a wide-gamut monitor too but for day-to-day use it makes no difference.) Even a 24Hz refresh rate is enough for text-based work such as programming, office apps or web browsing. So don't knock it till you have tried it!

4:3 is not coming back. Its old and appears odd today in the 21 century.

I suspect millions of Ipad users would disagree.

Not 4x3 but there is the 16x10 IBM T221, 3840x2400... I have three of them and I'd certainly buy a new monitor like this one if they'd made it with a sensible aspect ratio.

I wonder why my experience differs from yours - I have found almost all the applications I use (Firefox, PuTTY, Visual Studio, MS Office, TortoiseSVN) work fine with a simple 200% scaling in Windows 7. I agree that Remote Desktop is a pain.

Vista reverts to "fractional scaling", where it simply does a bilinear upscale of the application window, resulting in a blurry, god-awful mess where nothing was rendered natively.

I have to say I've never seen this on either XP or Win7. Perhaps it helps to have exactly 200% scaling so everything can be enlarged exactly. But as far as I can see, programs that aren't scaling aware (such as the command prompt window) are just rendered unscaled. Maybe it is because I have Aero turned off.

Not true. Windows can quite easily double resolution - just set your font size to 200% in Control Panel. Everything comes out twice as big but fonts are smoother. This has worked since Windows XP at least. I run it this way on a 3840x2400 monitor, so the effective desktop size is "1900x1200".

Its completely broken with perfectly legitimate local DNS URLs.

Can you give an example of a 'perfectly legitimate URL' that doesn't work? (Hint: all URLs begin with a scheme such as http: or file:)

People repeat this meme that desktop OSes don't support high resolution displays, but it's not really true. At work I have Windows 7 and several 3840x2400 displays; just setting 200% font size works fine in all the applications I use.

Well, yeah, surely 4000x4000 is 4k (like IMAX), and 3840x2160 is only about 2k measured conservatively.
