Like Sarah, I also love my iPhone. I don't like it how the iPhone 5 has a short battery span, yet it is a life genie. Take pictures for my articles, surf the Internet on the spot and do my banking mobile etc. Text people - love it. A time saver. I also love my MacBook Pro laptop too :)
I hate to admit it, but I just love my iphone. I think if there was a fire and I could only take one object with me, it would be my iphone. I can do so much with it - take photos, store photos, send emails and messages, play games, do my banking .. yes, I wouldn't want to do without it!
I love my laptop most of all; couldn't get on without it. I love catch up tv, the internet, and video games too. On a more practical level, I love technology that improves our help, our commutes, our ability to get stuff from the supermarket when we want it - things we take for granted and don't think about. We don't see them in our daily lives, but if they were not there behind the scenes, we would definitely know they were missing.
The internet, my laptop and mp3 player (I listen to audiobooks a lot now I don't have time to read paper ones much any more), but most of all my washing machine. I think the latter has made a massive difference to women's lives. I can live without a dishwasher but washing clothes would take up almost all of my time without a washing machine.
Oh and on the subject of stuff that changed women's lives, the pill is pretty awesome too.
I love my little 8" netbook by Samsung! Only recently I found out that netbooks are being made redundant and are being replaced by tablets! This is such a shame because my netbook is so versatile, doesn't get as hot as the tablets I have been exposed to and comes with a very sturdy keyboard for some solid writing sessions! Not to mention it is about 500 grams and very thin, easy to pack in its case and throw into my backpack.
