I guess they are left out on purpose. Those who are seeking cheap flights don't really need info about expensive flights. If you don't care about price, then just book directly from your favourite booking agency. On a sidenote, the service is most of the time identical across all the airlines, with a few exceptions, like not getting a meal during a flight (Ryanair!).

You didn't state where you live, but if you are in Europe, or travelling inside of Europe, then the best tool I've found is Azuon. It includes all the features you mentioned and more. Azuon is not free. If you want a quick and free solution then ebookers website offers in my opinion best free service, though, not nearly as good as Azuon.

Take it easy, please. On the web forums and Internet in general there are so many people who are not native english speakers. Of course there are times when you can definitely tell that the person didn't put much thought in whatever he/she was writing, but in many cases incorrect grammar does not really tell you about writer's intellect. It takes many years of practice to become fluent in any foreign language. Most of the time learners will never become as good as the native speakers. It's a better idea to judge people more by their message, not by the form.

So excuse me for my non-perfect english, I come from Russia, live in Finland and currently studying in Portugal. We just don't practice it in our daily lives ;)

You are comparing Windows XP (released in 2001) with KDE 4 (4.0 released in 2008).

I honestly don't know much about Windows, because I don't use it, but your comparison made me doubt if you really know what you are talking about.

Microsoft has got a couple of newer versions of their OS, latest of them is named Windows 7, which I heard does a many things better than it's ancestors, also having many UI improvements. ;)

That was quite an uninformed comment. Pressing Alt on Windows is same as Ctrl+F2 on OS X - you focus on menubar. Then you can use arrow keys to move around or press F, S or whatever you want to move directly to desired item.
We live and learn.

I believe OP was referring to trolleybuses. Trams need rail tracks to be built into the road, but trolleybus is just like a normal bus on rubber tires, except that it uses electricity as a power source and constant connection to power line is required. There is no need to tear up the road for trolleybuses, but the power line must be built.

The advantage ultracapasitor bus has over trolleybus is that it can drive further away (as far as capacitor allows) from it's normal route than trolleybus.

This is because Microsoft has around 90% market share in OS business, while Apple doesn't.
