I use only Macs so only Safari is used for browsing and Keychain also holds a whole host of passwords for applications too along with card data. It's hardly the basics, does 1password integrate with other applications and store login credentials for them too, like keychain does? I know you have your product to schill but I don't see anything 1Password does that's worth paying for over keychain sync.
On a Mac, that's something we'd like to add at some point. Integration with other applications. We can do it with iOS now so it'll make more sense if we can also integrate on the Mac. That said, I don't know what the plans are for this at this particular time on Mac. I know many of us on the team would love to see it as well though.
That said, we certainly don't mind if you use another product. Our stance has always been that you should use any password manager that is secure, even if it isn't our own. The benefits of using a password manager are worth it and we'll be happy even if you aren't using ours. All we've ever wanted to do was to help people and improve their lives and sanity by helping them securely store their data. If you want to use Keychain, we certainly won't try to stop you. That said, there is plenty that 1Password does that Keychain does not.
Some of the bigger reasons to use 1Password would be total control of your data. By default your passwords are synced only if you choose to do so. We also offer wifi sync for those who are cloud adverse and do not want their data to ever be in a cloud storage system. This is one of the bigger differentiators between us and Keychain (which naturally has iCloud prepended to it a lot these days).
We also offer support if something goes wrong. I'm not sure about you but I often have trouble getting real support with Apple software if I need it. Usually you're on your own if you have questions and Apple Store geniuses aren't always nearby for everyone. My nearest Apple Store is at least an hour away and I'm very unlikely to drive that far to get help with software questions. We have a full team of support staff waiting to help if you ever need it. I am one of them.
If you ever want to move away from Safari or ever get something other than a Mac, you'll find that you're more or less locked into Keychain at that point as there is no export functionality that is simple and to the point with Keychain. Your data is yours with 1Password and we export in our own 1PIF format, read by most other software, and CSV. No lock in from us.
Ultimately the choice is yours, but, we do offer a free trial for Mac so you're welcome to try it before you buy it. Let me know if you have any other questions, I'm happy to help, even if it's via private message.
1password people on here, you guys should have really made a proper sale and some of us might have bit and then stayed w you after iOS 8 got released.
iOS 8 and touchID will be my way since it's free and secure.
Proper sale? I'm not sure I understand how you can put free on sale

This is the iOS sub-form, right?
The iOS application is now free, with in-app purchase for Pro features (multiple vaults, custom sections/fields, viewing attachments, folders, tags and other great features). The price of that is also $10, $8 cheaper than we were asking for 1Password 4.
One of the biggest reasons I use 1Password over Keychain is the ability to integrate with Dropbox so I can easily find and use my passwords on any computer, Window or Mac. Linking it to Dropbox creates a file that acts as a light, standalone manager that opens with any browser. All I ever have to do is sign into Dropbox. Incredibly useful if you ever find yourself without your own computer (traveling, internet cafes, at a friends house, etc).
Being able to use 1PasswordAnywhere is pretty awesome isn't it?
It's also great knowing you have total control over where your data is.
Not to mention that all of your important login credentials are securely backed up.
I wouldn't necessarily say Dropbox or iCloud are backups, you should certainly be making local backups of your data if possible

The files in a sync service are constantly changing so they wouldn't necessarily be backups in the traditional sense. You can always restore to it but I wouldn't keep it as my only backup of your data.
I'm happy to go into more detail on this if you would like to know more about how I backup my data
