Acest blog infiintat in 2008 este si va ramane pasiunea mea principala. Sunt interesat de gadget-uri de orice fel, de la smartphone-uri, tablete, laptopuri si pana la sisteme audio sau camere foto. In plus, incerc pe cat imi permite timpul sa invat noi lucruri despre arta fotografica. De asemenea, voi incerca pe cat posibil sa relatez despre locurile frumoase pe care le intalnesc in calatoriile mele din vacante.
