iphone.. Is it really new technology?

I recently purchased iphone from AT&T. It has many functions. I can play games, check email, use it as dictionary, radio and of course cell phone. All digital electronic devices are in this small phone.
iphone makes me wonder if iphone is using dramatically advanced technology than other.
I think the answer is "no". Hardware is the same. Not really new CPU or memory chips are used. However, it has very well developed operating system and software. Not the brand new technology is applied to iphone. Instead its OS is developed to well interact with all existing software or information technology.

Do you remember the time you studied SAT?

I came to the U.S after I graduated highschool in South Korea. I entered community college, so I was not required to take SAT. I wondered what is SAT and I did search about it. What I found are online tutorials. They are cheap and have such a high quality in teaching. Since I never studied SAT I want to know about SAT and maybe I take one of free online SAT class for fun.

Here is a link for a online class.

I envy someone make money by doing what he/she likes to do

Some people really like what they do for their living.
I am not one of them. At least not yet.
Money or joyness, you may need to pick one of them. If you are lucky then you may get both. Some artists dont make penny from their works, but they are very passionate and love what they do.

I have not found things like I really want to do or want to be. Maybe I am not brave enough to forget about money and fortune. As long as I concern about money and its relationship with happiness, I will never be able to find one for myself.
