The current version is 1.1. The 7 reviews of it are mixed, with some users quite satisfied, others very dissatisfied. I see most of the messages of users send to Support. Some users write in to express their delight with DT To Go, others report problems with establishing connection for Sync, others report a variety of problems or make suggestions for future versions.
Let’s start with Sync issues. The majority of users have no problem establishing connection between the Mac and the iOS device and initiating Sync. I’m in that group. I use three Macs and three iOS devices (iPad, iPad2 and 2010 iPod Touch) and have two WiFI routers in use. (2010 AirPort Extreme and 2010 Verizon MiFi). Any of my iOS devices immediately establish connection with any of my Macs, every time, without fail.
But when I pulled an older AirPort Extreme out of the closet and tried to set up Sync using it, I sometimes had connection problems and couldn’t set up Sync. I wasn’t surprised, as the reason I had replaced it was that I was getting degraded performance and connection dropouts for Web browsing and file transfers on its network. Checking out Apple’s Support forums, I found this isn’t uncommon (and isn’t uncommon for routers from all manufacturers) - sometimes attributed to degradation over time in some of the parts used.
Switching to a local network created by the Mac very often solves connectivity issues. (Of course, there can be other problems such as an unstable operating system on the Mac, a damaged DEVONthink database or malformed files in a database.)
Later this year a new Sync procedure will be introduced to the DEVONthink applications, and will also replace the current Synch procedure (which is used by other iOS apps as well as by DT To Go), and I expect this will be more robust for connections in DT To Go.
Expectations: We emphasize DT To Go as a companion to DEVONthink databases on a Mac. It enables transfer of content for use on a mobile device, as well as the ability to take plain text notes and capture Web bookmarks and HTML pages, photos and even voice notes and sync them back to the Mac.
DEVONthink To Go is NOT a full implementation of DEVONthink on the Mac. It cannot be, simply because current iOS devices are not “trucks” (to use Steve Jobs’ comparison) like Macs. iOS devices have minuscule RAM compared to any of my Macs, and much less processing power.
My main DT Pro Office database contains about 30,000 documents. I wouldn’t dream of syncing it to my iPad, as the iPad would be terribly stressed and many of the operations that I use on the Mac simply can’t be done on an iPad. Features such as smart templates are not supported in iOS. There’s no memory “room” for See Also. Some of the document types I use cannot be displayed in iOS. Creation and editing of rich text isn’t supported in iOS. AppleScript isn’t available. The rich working environment of DEVONthink on the Mac cannot (yet) be created on an iOS device.
I doubt that I have ever Synced more than 3,000 documents to an iOS device, and normally Sync no more than a few hundred for use on travel or for a project.
But I find using DT To Go to let me carry selected content, add to it and send new content back to my database does extend the usefulness of my information resources, and for me that’s what it’s about.
Plans: Future plans include the ability to reorganize documents and groups, improve viewing of documents (especially PDFs, perhaps with annotation ability) and of course an improved Sync (which will also open alternatives to WiFi-only direct syncing between a local Mac and the iOS device). Tags?
The next maintenance release has a number of bug fixes and improvements and is awaiting Apple’s review and posting on the App Store.
iOS 5 will enhance usability of DT To Go. For example, I’m looking forward to the tabs feature of Safari, with the inclusion of Reader.
