This blog’s been on hiatus for a few weeks. While I was away from the blog, my wife started another semester of grad school. I’d been getting used to using our computer while she was on break, but now she takes our laptop to campus with her every day.
That leaves me with our iPad as my primary “computer.” I feel very blessed to have a second option to use when our laptop isn’t available. I know many people don’t have access to one computer, much less two.

But it reminded me of a question that I’d been thinking about earlier this summer: could I use a tablet as my primary computer? I’ve grown up using computers, first Windows, then Mac, and only within the last couple years have I been using a touchscreen interface on a tablet or smartphone.
Tim Cook, the CEO of Apple, recently said he does 80% of his work on his iPad. A tablet is considerably cheaper than a laptop with similar power. But to have only an iPad in the house, no laptop, wouldn’t I need to be able to do 100% of my work on the iPad? 80% wouldn’t cut it.
Now, I’d be shocked if the CEO of Apple doesn’t own a laptop (along with every other device the company makes). But he hints at a trend that’s been happening for decades: computing devices have become more powerful while also becoming smaller.
Tasks that used to require a desktop computer can now be done on a tablet, such as writing a report or recording a song. But not every task is doable on a tablet, and some that are doable just aren’t as efficient.
For example, I’m a video editor by trade. While I can do a certain level of editing on my iPad through apps like iMovie, it’s still not comparable to editing on a full-fledged computer. The iPad doesn’t have the storage space for all the video files I use, and the touch interface makes precise edits more difficult than with a mouse.
That’s why, for me, a tablet won’t be able to replace my computer…not yet at least.
So what do you use your computer to do? Watching videos, reading books, writing papers, and sending emails are all tasks that can be done just as well on a tablet as on a computer.
If you use a computer and only do those types of activities, you probably could go with a tablet as your primary computer.
You may find that particular workflows that are familiar on a laptop are not possible or not as easy on a tablet. But I think tablets have caught up to computers on most basic tasks.
One last thought: if a tablet is going to be your primary computer, don’t make a hurried choice. Make sure you try different ones and find the right size, operating system, and power to meet your needs.
Do you use an iPad or another tablet? What activities do you find more comfortable on a tablet than a computer? What about vice versa? I’d love to hear from you below!
If you have a smartphone, you probably know that your data plan is a big chunk of your monthly bill. But when was the last time you checked how much data you actually use? Are you paying for more data than you need?
What is data usage?
Data usage on a mobile device (most often a smartphone or tablet) is simply all information that is sent from or received by the device. (The exception is phone calls and text messages, which are counted separately from data.)
This includes text (emails, websites, etc.), audio (downloading songs, listening to online radio stations, etc.), video (watching Netflix, downloading a movie, etc.), and other uses (such as GPS navigation or downloading and using certain apps).
Here’s a good way to check what activities use data: put your phone in airplane mode. That way it can’t access any data at all. Certain functions will still work, like viewing photos you’ve taken on your phone. If a certain app or activity won’t work on airplane mode, then it needs access to data to work.
How much data do I use?
Now that you have an idea of what activities use data on your phone, you’ll want to find out how much data you’ve actually used in the past. Your monthly bill may show that, or you may have to log in to your phone carrier’s website.
Remember that many phone plans these days have begun counting shared data among all the devices on the plan. So if you have family members with smartphones, their data will also be counted toward the monthly limit.[1]
If you’re wanting to instead get an idea of what your data plan could be, or you want to know what activities use more data, check out one of these data calculators from the four major carriers. Pay attention to whether you are inputting monthly or daily usage for each site.
NOTE: data usage is the same regardless of which carrier you use,[2] so you don’t have to just use the calculator from your carrier. Feel free to try multiple ones; one might be more helpful than the others.
How can I limit my data usage?
If you’re interested in using less mobile data, I’ve got a couple of tips for you.
– Remember that different activities use very different amounts of data (as shown by the data calculators above). Downloading mainly text, such as emails, uses a tiny amount of data. You could check email all day long and not come close to your limit.
Sending/receiving photos (such as uploading a photo to Facebook or sending as an attachment) uses more data. Streaming[3] audio uses still more, and streaming video uses the most data of all. This doesn’t mean you can’t enjoy those activities, but it helps to know the next tip.
– Use Wi-Fi when possible. Data that your phone uses when connected to a Wi-Fi network (such as in your home) does NOT count against your data limit. So if you’re at home and your phone is connected to your home Wi-Fi network, stream all the music you want and download app updates at the same time; none of it will count against your total.
You will want to go into your phone’s settings and make sure that your phone is set to automatically connect to Wi-Fi networks it has previously used.[4] Also, check the status bar at the top of the screen to make sure that you see the Wi-Fi symbol before you start data-heavy activities. Below you can see it on Android and iPhone, marked with a green circle.

– Restrict apps’ access to cellular data. When you’re not connected to a Wi-Fi network, your data usage is considered cellular data, and counts toward your limit. You can restrict your phone from using certain cellular data.
Apple has made this very easy starting with iOS 7. You can tell your iPhone or just particular apps to only use data when connected to Wi-Fi. Apple has a customer support page explaining this.
As far as I’m aware, Android only allows you to limit data used in the background (explained here). This prevents an app to use mobile data unless you actually open it. The newest Android version also has nice visual charts of data usage.
Taking action
Now that you know data isn’t counted against you when you’re connected to Wi-Fi, are there changes you would make when filling out the data calculators above? If you save your data-intensive activities for when you’re connected to Wi-Fi, you may be able to use far less cellular data than you first thought. Maybe you can even downgrade to a less expensive data plan!

Do you enjoy reading this blog? If so, I’d love to hear from you! (If you’ve read this far but don’t enjoy it, I’d be glad to hear your thoughts, too.)
What topics do you want to learn about?
1 – Your total may be counted in gigabytes (GB), and lowest data tier from most providers is about 1GB. If your total shows up in megabytes (MB), remember that 1,024 MB equals 1 GB.
2 – T-Mobile recently announced that their customers can stream music through certain apps without affecting their data usage. That’s the only situation I see where data usage would be counted differently among the carriers.
3 – Streaming means watching or listening to something in real time, such as music on Pandora or video on Netflix or YouTube. The opposite would be downloading the audio or video file to your device, and then watching it. Both options use data, but more and more often people are consuming music, movies, etc. on-the-go by streaming them rather than downloading them.
4 – Keep in mind that you shouldn’t do any sensitive activity (such as online banking or sending confidential information) unless you are on a Wi-Fi network with a secure log in and that you trust. Not McDonald’s free Wi-Fi!
