Chromebooks are inexpensive, they keep you up with the world even when you’re on the go, and there’s no fear of data loss. Neat right? But a Chromebook isn’t crafted to deal with high-end apps.
They say never bring a knife to a gunfight – and they’re dead right.
There are times when you need a real PC – one with a benchmark processor. Photoshop, AutoCAD, gaming, Autodesk Maya, video editing tools; these are just a few things you just can’t run on a Chromebook.
So when to know this is not the 
When You Have specific Work Requirements
Some apps aren’t made for Chromebooks. For instance, if you are learning specific software and your Chromebook doesn’t support it, you will either have to rely on another computer or get a newer laptop altogether. Similarly, using Pixlr when the whole institute is on Photoshop, your learning curve is going to get a lot steeper.
When You Need Sheer Power or Compatibility
Just what I said a while ago – gaming, video editing and tasks that demand power and a solid processor cannot go hand in hand with a Chromebook. Also in times when Chromebook can’t run your program or does not allow you the desired connectivity because of its lackluster compatibility, you will again think of getting another PC for those tasks. If you need a single machine for everything, and I do mean everything, get a better notebook.
When You Need More Resale Value
Chromebook, out of the box, feature an average or an above average set of specifications at best. And if you are hoping to make some money and add a bit more for a newer Chromebook, it’s less than likely you will have your wish. Unless you are buying it for long run, so you can repurpose it later, get something that has a better resale value in case you decide to sell it.
When Chrome isn’t your Operating System
Can’t please everyone. Despite being a great OS, Chrome can’t fill in every pair of shoes. There are millions out there that are familiar with Microsoft’s dominating Windows OS. Then there are another couple of millions that have vested their time in OS X.
So if you are more familiar with one of those established OS and don’t want to put it time to learn how to download .app files and install them on a Chromebook, or if you don’t want to feel left out in a classroom where everyone but you is using a Windows laptop, get something else.
Can I Test-Drive Chrome OS?
You can. If you have a decent laptop from a few years ago, you can try it out and see if it works for you. This will help you reach a smarter decision.
Plus, you always have an option of keeping two machines – one for hardcore tasks and other, on-the-go. But if you are looking for one machine that does it all, get something other than a Chromebook like a high powered laptop from HP, Dell, Acer or Macbook by Apple Inc.
