Lets users stream music, videos and photos to their iPads.
Apple didn't announce its long-rumoured 'cloud iTunes' service last week, but PC World is the latest company looking to fill the gap.
The UK retailer has launched an iPad Media Streaming service, which lets users store up to 100GB of music, video and photos in the cloud, and stream it to their iPads.
The service is the work of the company's TechGuys division, together with online storage company Livedrive. It costs £39.99 a year.
Besides streaming content from the servers, iPad Media Streaming lets users also access music, video and photos on multiple home PCs and Macs from their iPads - getting in before Apple's similar AirPlay feature, which will debut later this year.
PC World's launch follows the debut of Music Anywhere from Carphone Warehouse - a cloud service focused specifically on music, including an iPhone app.
