HandiNAVI
From Serial Experiments Lain wiki
The HandiNAVI, also Portable NAVI, is a tablet-style NAVI. Mizuki Alice and Iwakura Lain each use one; in fact, they use the same model, according to Visual Experiments Lain. Lain's HandiNAVI becomes heavily modified as the show progresses. Alice's features a dolphin key chain attached to its strap. Taro is also seen with a HandiNAVI based on a toy gun.
