Review: Sanyo MM-5600
The MM 5600 is for people who want all the power user features, or what they think are the power user features, but are not power users. Without Bluetooth or PC syncing or any email client, the MM 5600 will not meet the needs of true power users. However it will meet the needs of people who want lots of powerful sounding, and even useful features. The screen alone will impress their friends and coworkers. It will also be great for people who love to snap pictures.
Unfortunately these not-quite-power users may become easily frustrated with the difficult to understand organization and naming conventions of the settings menus should they decide to delve into customizing their phone (and most do). But no one uses settings as often as they use phone applications, and the MM 5600 has very good contacts, messaging and browsing.
The size of the 5600 isn't too much of a problem, even though it is a bit large. It's a tight fit in small pockets. At least the camera, screen and battery life are all excellent, justifying the bulk. Plus the size the MiniSD slot adds pays off as storage for pictures and media.
