Rpis are very popular fitness trackers. They are cheap and easy to wear. All you have to do is charge it overnight and you are good!
Most rpi s can be bought in bulk through online retailers or through certified sellers such as through Amazon. If you do not want a dedicated alarm function, you can easily opt for a none-the-less simple wristwatch or even an iPhone app.
This is not the case if you want an alarm function as this needs a smart alarm device.
The price of a rpi depends on the quality and features that they have. Some have less features and some have no alarm function due to the price difference.

High demand
As the demand for RPI continues to grow, more companies are looking to acquire them. This is a profitable venture for them as they can charge higher fees for their product or service compared to those who do not use RPI.
Since only a small number of companies have access to the hosting and infrastructure required to run an RPI, it has value. As more companies adopt Rpi as their hosting platform, the value will continue to grow!
Unfortunately, since only a few companies can afford the high costs associated with running an Rpi, it is very limited in its reach.
Not compatible with many devices
Although it works with a few devices, the Raspberry Pi is not compatible with most machines. It must be connected to a power source in order for it to work.
This is because the Pi requires a user-level account and password in order to login! This is important as you can now save your credit card details so that you can purchase your own Pi later on.
However, this means that you have to find an internet connection for your new Pi! You will have to set up an email and internet access set up as well as inputting your password.
Requires setup
Setting up a Raspberry Pi is another large expense that you will be taking care of once you have it!
There are several ways to set up your Raspberry Pi. You can buy a pre-assembled unit, you can purchase the components separately, or you can purchase both together.
Pre-assembled units come with all the parts and pieces needed to put it together and make it ready to use. This saves you time and resources that would be needed to acquire all of these components separately.
If you already have some programming experience but need a new skill set to grow on your Raspberry Pi, buying the components separately allows you to pick new courses or courses on your unit that allow you to grow.
Slow processing speed
Another big reason why Processing is expensive is the way it processes images.
Processing requires a special image format called HDR, or High Dynamic Range. This format allows the processing software to combine several photos into one, allowing it to process more details in one picture than others.
However, despite its high cost, only the latest versions of Processing support this image format, which is a shame because it can slow down the software considerably when processing.
Most free photo applications do not support this image format and will fail to create an accurate HDR photo every time.
Older version
The first version of the Raspberry Pi was released in 2012. This was an older version that was difficult to use. There were certain features that were not present in this newer version.
So, while this did not help lower the cost of education, it did reduce its usefulness. In order for students to learn new things, they would have to purchase an additional Pi.
Since it was so expensive, only high-end schools or educational institutions could afford it. Now, it is 2015 and the new model has been released. Both the old and new models can be used, but the newer model has more features that older ones have!
The new model has a power supply that is built into the computer, instead of being connected via a cable. It also has a hard drive storage system that is built into it, making it easier for teachers to storage materials for classes.
Costs money to run
Aside from the cost of the hardware you need, Rpi also costs money to run. You will need a good amount of storage to keep your server running, and you will need regular maintenance to keep it running.
Running a server is not cheap! Depending on how large your server is, you could spend as much as $10 per hour in upkeep and hosting fees. Plus, while hosting is expensive, building your own Rpis can cost you even more due to the software development costs.
In conclusion, if you are looking at building your own Rpis, consider investing in VPS or dedicated servers if you are currently located in China or Korea due to higher hosting costs.
Limited number of applications
Most devices have a handful of pre-installed applications that you can access and use right out of the box. These may include a messaging app, an audio or video player, a note-taking application, and an editor.
You can easily add your own applications as new apps in your device’s app store, making this feature even more valuable. In fact, there are hundreds of apps available on the market!
These apps are great! They can make anything you watch or read easy to follow and use. The latest version of the app for Android has some great features like Built-in Tutorials and Support for Different Types Of Users.
However, there may be times when someone does not have such an application installed. It is hard to explain why something is limited or expensive if you do not have it yourself.
Difficult to use
Despite being one of the most popular open source projects ever, Raspberry Pi is still a tough platform to use. For instance, there are no easily accessible tutorials on how to install Node.js or how to create and run a node server!
This is completely against the Pi’s intended purpose: as a entry level server solution. As a beginner, you will have a hard time learning how to use it if you do not have some experience with programming.
It also takes some time to get used to the different features of each distro because there are so many options! Some may be overwhelming at first.
