While the Dell laptop clearly has more +computing power, I preferred the Chromebook for a few reasons: -Now excuse me while I go waste more time scouring the web for more obscure but -brilliant apps. +* **Lightweight**: it’s only 2.4 pounds. That feels like nothing compared to +the 5.5 pound monstrosity that used to weigh down my backpack. +* **Battery life**: officially it’s 6.5 hours, but I’ve seen up to 9 hours +before. It’s very freeing to not need to plug in my laptop everywhere I go. +* **Size**: the screen is just 11.6” and it’s 0.7” thin. I honestly didn’t +think I’d prefer a smaller laptop, but the experience has been a lot better in +general. +* **Screen Resolution**: even though the screen is smaller, it’s still 1366x768 +-- the same as my Dell laptop. Resolution is very important to me: higher +resolution means I can fit more information on the screen, and my young eyes +can handle the smaller text. Going back to my Dell feels like looking through a +magnifying glass now. +* **Trackpad**: I use an [Apple Magic +Trackpad](http://www.apple.com/magictrackpad/?) at work, which is heralded as +the best trackpad out there, and in my opinion the Samsung Chromebook has a +trackpad that’s just as nice. Don’t even get me started with how horrible the +Dell trackpad is; I had to disable it and use keyboard shortcuts for everything +instead. +* **Keyboard**: the Chromebook has a keyboard that closely resembles an Apple +keyboard, and it’s hard to describe exactly why, but the feedback just makes it +feel *nicer* to type on than the one on my Dell laptop. Also, the search key +that replaces the Caps Lock key is really useful. +* **Price**: all of this great hardware for just $249 seems unreal. I’m sure +this is what converts many people, and it’s good to know I can do everything I +need to on a laptop that’s under $300. +* **Perks**: as an aside, Google also gives you 100GB free Google Drive space +for 2 years and 12 free Gogo passes with the Chromebook, which definitely comes +in handy. + +

+ +While that all of that is nice, the Chromebook still only has 16GB internal +storage, no DVD drive, no ethernet port, and hardly any processing power. And I +still need to be able to code and write on my laptop and access specific +programs that only run on Linux or Windows machines. ChromeOS has a lot of +things built in to get around these limitations, but some things require a bit +of tweaking. If anyone has read my past posts, they know that I am obsessed +with configuring things. Here is what I came up with for everything I would +ever need to do on my Chromebook: + +###Writing### + +I spent a lot of time downloading +[various](https://chrome.google.com/webstore/detail/write-space/aimodnlfiikjjnmdchihablmkdeobhad) +[writing](https://chrome.google.com/webstore/detail/writer/pnengefjfhgcceajaepbjhanoojifmog) +[applications](https://chrome.google.com/webstore/detail/writebox/bbehjmjchoiaglkeboicbgkpfafcmhij) +from the Chrome Web Store, but nothing seemed to work as well and seemless as +the stock Google Drive documents application.

I made a couple templates that expand the page out to almost +100% and resemble the colors of the OSX IA Writer app: one in [Gentium +Basic](https://drive.google.com/previewtemplate?id=1N7kZhXsYJoVJpt4rE5q7Xhp92M4DPB_-u2dOSkEAeRY&mode=public) +and one in [Open +Sans](https://drive.google.com/previewtemplate?id=1aX8UcUXpbiZD1HuTIofb8ookw6TYykWi50k47BTX6yk&mode=public). +To create a new document based off of a template: have a document already open, +go to the “File” menu, “New…”, and select “From Template…”. It’s kind of a +hassle though, so I often just stick to the default style. It’s a sign that I +am procrastinating if I’m trying to look for the “perfect template” to write in +anyways. + +###Programming### + +I’ve gotten so used to [vim](http://www.vim.org/) in a Linux +terminal that I don’t think I could ever use any other editor.

I haven’t had the need to try it +out yet, but it’s nice to have around for when I do. + +The best thing about coding on a Linux box through a Chromebook is that I still +have all of the great chrome apps and extensions right at my fingertips. +Especially when some apps can be opened up in small panels in the corner of the +screen temporarily. + +###Panels### + +Chrome recently released a new concept for opening new windows +called “Panels”, and once I discovered them I couldn’t get enough of them.
