Well. When I first started going to school I had a bit of extra money to save, but neither the time nor the capital to manage a stock portfolio.
I could've
a) taken a 5-year GIC with my normal bank, or
b) put my money into ING for
better interest, and been able to load or unload money whenever I wanted with a turn-around of about two days. With no fees.
Hmmm, a toughie.
Basically, I use ING to dump in money I will need soon or don't have time to bother investing. And since I can throw money into it at any time, I can put my money to work more easily and regularly than I can with purchases of bonds or T-bills (and load the account at the end of each month

). It won't replace all your financial needs, like stocks, cash machines, etc. etc. I wish I could just write cheques out of my ING savings account, but unfortunately, I don't believe you can.
Jam it back in, in the dark.
