Geary is an e-mail client. You know. The thing you used to read email in before everyone moved to Gmail. Some application that sits in your computer as opposed to running from your browser.
I've been using Thunderbird for years, with a slight break towards Gmail (though I'm back to ThunderBird now). And now I use to handle multiple work and personal email accounts. Here are some thoughts I have about the pros and cons of using a desktop email client:
- Your e-mail is available anytime, even without internet connection or when the site is down.
- You have a local backup of all email ever sent, in case someone hacks your account or locks you out, they can't delete your local copy.
- Desktop clients seem to handle multiple accounts a lot better then web clients. You can organize your view so you don't get confused between different accounts.
- Nobody can just decide one day that your client is no longer supported and change how it looks. If you don't want the change you don't have to upgrade.
- They can integrate with your desktop (i.e. notification)
- Updates are slower since applications are less flexible than websites.
- Desktop applications use more local resources than websites. Whether it is hard-drive space which is consumed by the local copy of the files (can be GB), memory required by the app to run(although Gmail is a huge memory hog) or CPU to do searches which on websites would have been done on the server.
- If you ever switch an application metadata you have in one might not be consistent with the other (like tags).
