I've had a Magic Connector for a few months now (the magnetic version), and wanted to give my thoughts on it. I liked it a lot at first, but the magnets never felt as secure as I wanted. The keyboard and trackpad would wiggle around a little bit while in use or when moving the whole setup around, and just didn't feel as secure as I would have liked. One of the magnets actually came unglued a little while back, and some of the other magnets are no longer very securely attached. I could just reattach the magnet(s), but in addition to the aforementioned issues, I've come to realize that having the trackpad on the right side of the keyboard is not ideal for me. It's much more comfortable having the trackpad below the keyboard, the way a Macbook is laid out. So I'll be using just the keyboard and trackpad for the time being, without a Magic Connector or anything else. Sadly, the BulletTrain Express seems to still be the best option out there, but it's not quite ideal for me, which makes it's very high cost even harder to swallow. Hopefully a better alternative will come out before too long.
That being said, If you don't mind having the trackpad to the right/left of the keyboard, I still think the Magic Connector is a really nice option, but I'd recommend the velcro version, which I assume will be much more secure and stable than the magnetic one.
