The turnover rate for any of the electronic devices often makes me hesitate. The only thing that plays a bigger role on when I buy or don't buy, and what I buy or don't buy, is my ability to afford the device when I want to get it. With a lot of us, this fast rate starts to be a real turnoff in general. But as long as there is a market for newer and better, the manufacturers will continue to speed up the process.
It doesn't have to be a turn off. The more rapid the update, the more likely it is that you will receive little, if any, benefit to make it worth your while to update. Thus, YOU (not you in particular, but in the sense of the YOU that is US) need to realize this and keep your money. There are zillions of others that might not have had the funds to get the last update, or felt it didn't offer enough for them to spend the money at that time. Companies have to trust that we make informed decisions and act in our own best interest. They cannot force us to buy everything they sell.
When I look at the lovely display on my retina iPad 3 Gen, there is no way I'm dumping it to get another almost exactly like it. The extra speed is not going to do much for me, based on my day-to-day usage. I will be much happier if I wait for the next cycle to see if they can entice me.
Now, for me, the Mini offers something that I want...so I can see my way clear to buying it.
I just heard about the Google Nexus 10 announcement....it looks a bit underwhelming for my needs....so I think I will just live with my Google Nexus 7...but I may take a look at the Nook HD tablet, just to see what it's features are.
Microsoft is coming with the Surface....got to admit it is intriguing...but the RT model won't work for me...and the Pro models like like ultrabooks...and since they will run i5 and i7 processors, I'm thinking they are going to have heat dissipation issues. I'm going to sit back and let others be the beta testers, as I have plenty of laptops that can run Win8, which I can get for a mere $40.
If I had an iPad 1 or 2 right now, I'm be hard pressed to not get the 4 if I had the cash. But with the 3, I see nothing compelling. If I spent a lot of time playing games, I might want to look a little harder. I'm sure there are some hardcore iPad gamers what might want to update, though. For that group, they have to make a decision. It could very well be worth it to them.
