Apple, Samsung, Sony and SanDisk are locked in competition for the MP3 player market, at least in Taiwan.

A report reveals that players made by those manufacturers now dominate Taiwan's MP3 player market when it comes to devices with capacities of 1GB or higher.

The report explains the local market is now "dominated" by these brands, leaving smaller manufacturers to compete with players of 128MB, 256MB and 512MB capacity.
