More and more technological devices developed nowadays appeal(ed) to people of its function and entertainment. However, we should wait until many have acquired it., the reason are as following.
Firstly, when the first production come into the market, a lot of people will crazily rush to buy it. These people will be the first (customers) to use the production before we know (new features and functions) about this product. So they will have whether good or bad experience about the products. We can (know) these products(用well 或者 better) according to their experience. If the product is not as good as we think, we will have other options (这里换个词来说,用options可能比instead要好一些。). However, while we buy these products right away, we may regret our action after we found these problems of it. So waiting is the best choice for us to make consideration(这里会不会用the decision更好一些呢?).
Secondly, the second one is better than the first one(感觉这句不是特别必要,可以直接把后面那句跟上吗?或者可以说 the latest devices will always be better than the previous one). Because products will be improved and perfected by updating it(them). The first one must be incomplete and faulty.(这两句可以并起来喔, later products will be improved and perfected by updating them while the previous one must be out of fashion or within bugs.) When people bought (the device,这里代词容易混淆,建议直接说device吧。) initially, some of (the customers) will complain about it to the company which would accumulate these advices and amend these defects. Hence, the latter the product produce, the better they are. Therefore people will buy better ones using same (amount of money).
Thirdly, the price will decrease after a long time. At the beginning, many people will be curious about it and buy it immediately so that the price will continue to increase until lower numbers(less amount) of people buy it. For selling more products, company have to (这里decide比较主观,但是公司一般都会是迫不得已的,所以用have to吧) decline the price of products to attract people. Thus we can buy the same thing without wasting money.
In sum, we will wait until many have acquired (device) that we can save money and get good thing.(better ones,在这里重复一下题目是不是更好呢?)
