practical concerns

I am faced with a dilemma. Despite $300 repairs and cleaning, sensor on my large Nikon D70 camera is still dirty. So all my pictures are ruined with a black spot in the right top corner. I am thinking about sending the camera with an extra lens back to New York. I still have my pocket Panasonic Lumix with me. That would mean a lighter daypack, more space, less worries about being robbed, etc. I don´t make money off my photographs, so why all this pain? Uploading large images in random Internet cafes with shitty screens and slow Internet connection is really painful. Even blogging is harder than I thought. Going absolutely offline is tempting.
