Feel free to take a second look. Haven't you seen this arched shape somewhere before? That's right, Logitech's mobile rodent is strikingly reminiscent of Microsoft's Arc Mouse. However, while the latter can be "flattened" for better portability, the Mobi Fold—nomen est omen—literally folds...

The idea behind the Mobi Fold is clever. Setup, configuration, and the folding mechanism are well thought out. Unfortunately, it fails when it comes to ergonomics. The clicking is too strenuous, and the shape is too angular. Added to this is the very high price.
