 If you have a reasonable capacity internet link at home or in your office, you can certainly run a Lightning node there. Any "broadband" connection is sufficient for the purpose of running a lightweight node, and a fast connection will allow you to run a Bitcoin full node too.
 
 While you can run a Lightning node (and even a Bitcoin node) on your laptop, it will become annoying quite fast. These programs consume your computer's resources and need to run 24/7. Your user applications like your browser or your spreadsheet will find themselves competing against the Lightning background services for your computer's resources. In other words, your browser and other desktop workloads will be slowed down.
-And when your word processing app freezes up your laptop, your Lightning node will go down as well. Furthermore, you should never turn off your laptop.
+And when your word processing app freezes up your laptop, your Lightning node will go down as well leaving you unable to receive transactions and potentially vulnerable to attacks. Furthermore, you should never turn off your laptop.
 All this combined together results in a set-up that is not ideal. The same will apply to your daily-use personal desktop PC.
 
 Instead, most users will choose to run a node on a dedicated computer. Fortunately, you don't need a "server" class computer to do this. You can run a Lightning node on a mini-PC, such as a Raspberry Pi or an Atom-based fanless PC. These are simple computers which are commonly used as a media server or home automation hub. They are relatively inexpensive, costing between $50 and $150 USD at the time of this writing. To run on a mini-PC, you will need an external USB hard drive, which again is relatively inexpensive, costing approximately $50 USD. The advantage of a dedicated mini-PC as a platform for Lightning and Bitcoin nodes is that it can run continuously, silently, and unobtrusively on your home network, tucked behind your router or TV. No one will even know that this little box is actually part of a global banking system!
