Here's the problem: I have $90 saved up which I can use to buy a 2GIG or I can save up some more to get a 4GIG online. But the problem is, I don't have a credit card and I don't know if my friend will let me use his. Now this is the hard part: should I buy the 2GIG now and save up for another 2GIG or just buy the 4GIG? If I were to get 2 memory sticks, I would have to switch them around constantly and I usually don't like carrying 2 memory sticks when I'm outside. But if I bought the 4GIG and it gets stolen(which happened before) or malfunction(which also happened before) all of my money would go to waste. But that wouldn't be the case if I had 2 memory sticks. So what should I do, buy a 2GIG now and save up for another one or just get the 4GIG?
