If you buy shares and wanna check how much you earn or loss, some business news, and keep track of all your shares...
Bloomberg is good. It is free. So, your share prices only updated after 20 minutes. I like it. To search for your share code is easy. To add also easy. And you can get any share code from all over the world. Singapore, USA, UK, Hong Kong...

Another one I like is Zinio. It is a virtual magazine software. So, if you used to buy a lot of imported magazine... including Penthouse and Playboy, you can easily get your digital copy here. I got US Maxim for USD8.99 for 12 issues! My credit card charged me RM26.xx for this. Ha! Ha! So, RM2.20 each issue.
Playboy and Penthouse kinda magazine more expensive la. He! He!

One more...
TeamViewer.
This is a very simply application to set up for computer illiterate like me. It is free for private use but they say if for company use, you need to buy it.
This software is for you to access to your laptop, pc, imac and control it from anywhere in the world. Meaning you don't need to bring your heavy laptop when you are on work travelling. You still can access to your computer and get some document and send it out as long as your laptop or PC is connected to the internet and your ipad is connected to the internet. This is when 3G comes in handy.
There are many similar software like this but seems like this is the easiest to set up compared to others.
