A:Answer Absolutely. If you can write a book, you can type it on this laptop.
Many options for managing your text, including myriad web-based and ChromeOS apps. Mainstream apps, such as MS Word, and many others. Most Android apps are supported, so if you already own those, you can use them here, using the same Google account.
You've got 64GB of hard drive space, space enough for several novels.
Also syncs with Android devices, in case you're writing on multiple devices.
The hard part is actually writing the book. ;)
