In last week’s Top Tips 2, we mentioned that we watch movies on our iPad from a separate hard drive and some of you have asked “How?”

Here’s how: It’s called a Kingston Mobilelite and it costs about £40. You load your films, music, photos, home movies and files onto a hard drive (or onto a USB stick or memory card).

You plug the hard drive into the MobileLite and it uses WiFi to talk with your tablet or phone. That’s it. The hard drive in the picture has a huge capacity (2TB) so it holds every photo, album, movie and file that we have. If Apple sold an iPad with that much memory, then – at their current rates for extra memory – it would cost £7,000.
