As John Gruber writes for the Vesper blog, the big new feature is sync:
We’ve tried to make it as easy and simple as possible to use. Here’s how it works. First, you create a Vesper Sync account using an email address and a password. Then, your Vesper data — the text of your notes, your image attachments, your tags, everything — syncs to our cloud service. Sign in using the same account on another device, and your Vesper data will appear on that device.
Great news, to be sure, but I’m a tad disappointed. Gruber continues:
We have several ideas for future Vesper clients, but we’ve decided which one we’re going to tackle next: Mac. We did the iPhone version first because the iPhone is the one device you have with you everywhere, and we remain convinced that was the correct decision. Ubiquity is essential to a notes app. The Mac, though, is the device where we’re most productive.
The Mac may be where they — “they” being the Q Branch gang — feel most productive, but not me. It’s only one nerd’s opinion, but I would much rather see an iPad version. As someone who works more from my iPad Air, it would be neat to have an iPad-optimized version of Vesper. Yes, as Gruber says, I can run Vesper as it is today on my iPad in 2x mode — and it is something — but I like to lament my first-world problems.
