Open cards that I can not seem to see

I have no visable open cards, I have no access to apps because I have too many open cards, I have nothing but 5 icons on my phone front screen,  the green phone the envelope the contacts calendar and a black arrow that opens applications, there is nothing open on the screen, and nothing to flick, where are these open cards?

For a device that uses solid state storage with a decent speed, there is no need to keep programs in memory after they are closed.
From my experience, in terms of use, the webOS is easily the best mobile OS when it comes to the UI, for performance, it falls behind the ios android windows phone 7 and windows mobile
HP could have had a extremely good tablet if they used a better front facing camera and added a rear facing camera (there not only good for taking pictures but they also work for scanning qr codes)
Then when designing the OS, have the company which created the CPU, to release a special batch for your developers where the firmware will be altered so that the chip runs at 300MHz max, then install only 128MB ram.
The reason behind this is, if you can get the developers too design a OS that runs snappy on that hardware, when it is put on the full 1.2GHz hardware with 1GB memory, it will be insanely fast.
I have attended programming classes in college and the modern programmers are taking a turn for the worst. hardly any effort is put into optimizing code to run fast, instead they rely on faster hardware being used to make up for the poor code.
In the "old" days, hardware did not have the exponential increase in speed, programmers had to write code that that used as little space as possible as storage was very expensive. Programmers also had to make the code as efficient as possible because processors were slow.
If programmers kept this mindset today, we wouldn't have operating systems that take 20GB of hard drive space and usee 1GB memory just for them self.
we also wouldn't have mobile OS that use 300MB memory just on them self.
