iTwin - In Use, Security and Verdict
The iTwin's performance is reliant on the speed of your broadband connection more than anything else. In transferring a file from one to computer to another, the host has to upload as the second computer downloads. Effectively, the iTwin turns your computer (the one storing the file being transferred) into a server.
The connection is reliable and the communication between the two halves of the device is very quick. If the software has already been installed on a computer, it only takes a few seconds for the two to perform the necessary handshake. However, this arguably isn't enough to justify a £100 outlay. Forgetting full cloud storage solutions like Asus's Web Storage and HTC's Sense storage, and standalone options such as Rackspace and Dropbox, many people's needs can be met by simply using Gmail (using the classic emailing yourself an attachment method) or services like YouSendIt.
What the iTwin has over these is a different approach to security. The connection between your two computers is secured with 256-bit AES encryption, and as there's no data stored anywhere apart from the hard drives of the sender and recipient, there's no way for data to slip out accidentally. You can also use a password, so that plugging each end of the iTwin isn't enough to get them talking.
There's always the chance that you could lose one end of the iTwin, but should that happen you can deactivate the lost half using your remaining half. And if both go missing, you've only lost the hardware as the iTwin itself doesn't store any data. A neat, much-welcome addition is that its makers let you buy a replacement half iTwin for half the price of the full package. No extra fee lurks aside from postage and packaging.
However, in spite of its simplicity of use, its sound integration with Windows and overall reliability, we think few will be able to justify the initial expenditure. There are no costs to incur through normal usage in the future, but when your computer has be left on throughout the day in order to make your on-the-go half of the iTwin useful, it's not the easiest device to slip into your lifestyle unless you already have a reason to keep your computer on all day long. And if you do that already for no particular reason, think of your bigfoot-sized carbon footprint for once.
We'd find it easier to recommend if it shed £30 off its price tag, but unless a big-name alternative decides to one-up iTwin such a price cut probably won't happen any time soon.
The iTwin does what it sets out to do well, connecting two PCs over the web securely, irrespective of their position in the real, living, breathing world. However, the fairly high price and functional limitations of the technology - primarily having to have your host computer on all the time - limit its appeal.
If security is a key concern, the iTwin has what you need. But if it's not there are plenty of good, free Cloud storage options out there that will do the job for most personal use applications.
