Plenty of reasons; its small & compact, looks cute, different from the normal slab style phones that everyone has become used to, and it has a screen that folds which does look fun and futuristic.
Ive been waiting to buy one myself, but the prices have just been to dear until now with this one and future entry levels coming out.
I would 100% recommend professional laser instead if you're happy to save up. Its far less painful than epilating, much better than shaving as well and after 6-8 session you'll be far less worried about hair as it grows back so thin.
