Well here's how I would think my way through.
My generic answers for both would be:
- If the gadget you are buying is within the 70% or 80% budget cap that you put on expenses (remember the 10-20-70 or 30/70 or 20/80 rule?), then go for it. You should make sure that the gadget or item you want to buy is within that expenses bucket.
- If the gadget you are buying is something you can use to increase your productivity and/or generate income from, then go for it. For instance, you don't have a laptop you can use when you are doing presentations to your clients. Then indeed, you need one.
- If the gadget is reasonably priced, and I mean, a true SALE price. Imagine an iPad that usually costs around 400 USD and it is being sold at only 200 USD! However, go back to the first two items I've written here: Is the purchase within the budget? Is the gadget something you need and will be able to maximise use for?
On the whole, I would also say this in terms of purchasing some goods. Go for QUALITY over QUANTITY! We often fall prey to those SALE items that we see in malls but we often forget whether these items will last or not. A classic example: My mom saw a set of four cooking pans for sale at 2,000 pesos (around 45 USD). She bought it because it's on sale. We then went home and used the frying pan. After just one usage, the pan was deformed, and it could no longer be laid flat on the induction cooker. What a loser product, right?
So there goes my tips for the day. :-)
