iPad Review

I had been waiting for iPad2, but due to the devastating earthquake hit Japan, the sale has been postponed. I really wanted iPad to read pdf files, for computer science. And the first iPad became less expensive, and I though that was enough for me to just mainly use it to read pdf files and web browsing. I didn't have to get the iPad2's new feature that is thinner and lighter, and faster. And here is the review of the first iPad.
In conclusion, I am quite satisfied with that, it is amazingly fast, and thin. and the display is very beautiful. And I feel basically no delay of processing. I now use it to read news sites every morning with coffee, it is much more readable than to read on laptop, reading things on laptop was really painful for me. So I printed out pdf files, and now I don't have to, it's eco-friendly. And I use it for reading comics. and read pdf files and books with GoodReader, Almost these things are my main purpose of use.
Now, what I am a little unsatisfied things, when using Safari, and open multiple pages, when go back to other pages, it automatically reload the page, and that makes it slow. But I could avoid this by buying browser app, I bought "Mercury". Next, it sometimes happen that app suddenly halt and go to the main place, the apps shelf. This is because of lack of memory, iPad has only 256MB, but this is acceptable if I regularly delete unused apps or reboot iPad.
Now with this magical things, every single piece of free time became something with iPad, because of its mobility, it's so thin, light, fast. I can not live without it now. But I have read the article about this, that was having no empty time is not good. With empty time, our unconscious starts to roam, and I feel that. And the author returned his iPad, but I won't, but I will be careful not to use it so much, like watching before sleeping, or seeing something unhelpful to me with web browser. Or reading "2ch". It is sometimes so much more important to me to do something different instead of iPad.
