Yes, I can definitely expand on those subjects - I just didn't want to go into more detail on a subject you didn't originally ask for unless you were interested.

1. Indoors, I imagine your temperatures are above 60 or even 70F (sorry, my Celsius knowledge is sorely inadequete - 23C?) year round. If the tree senses colder temperatures below a certain level, the tree will drop its leaves and go dormant like all the oaks or maples. If the tree is only exposed to the warmer conditions, the tree will mostly maintain its leaves throughout winter.
   
   
2. Indoor conditions are very static compared to outdoors. There is less airflow, less temperature fluctuation, less difference between day and night cycles based on artificial light use, and generally less light in total compared to outside. Trees have evolved to grow best outdoors and although outdoor trees are more susceptible to pests and weather, we as bonsai hobbyists can monitor conditions to help our trees if their natural defenses fail or if a unseasonable storm is coming. The light, temperature, and humidity outdoors compared to indoors especially I think contribute to our bonsai growing faster and being healthier outdoors. A lot of indoor bonsai especially away from windows are less vigorous and that means they may be less tolerant to a mistake on your part of watering or may die of their own accord.
   Also, make sure any tree you keep indoors is tropical. Junipers are commonly sold to beginners as bonsai, but they are advertised by those who don't know better as indoor trees. Such species need winter dormancy or they will eventually die.
   
   
3. Thanks for filling in your flair - I hope you will enjoy your bonsai and grow in this hobby with us!
   
   
4. I don't know exactly how amazon works over there or if you will have the same sales as the US, but I was recommending some beginner books to someone else recently and noticed both are on sale. I highly recommend a thorough beginner book to help you with basic concepts when starting out.
   This is the book I first got when I entered bonsai many years ago - still good and sustained my interest even after some initial trees died.
