I’ve been enjoying mine, but I won’t say it’s without fault, though I’m pretty certain it’s just slightly buggy software.
I’ve run into losing the cursor a few times and having to restart to get it back (not since the most recent OS beta however). I’ve also noticed today a strange problem with scrolling in certain applications. In Twitterific, sometimes two finger scrolling with the trackpad becomes lethargic or unresponsive. 3 finger switching is snappy as ever, so I’m fairly certain it’s a software bug, but I noticed it in another app as well.
That said, I would still highly recommend it, as it turns your iPad into a true laptop replacement. I give it like a 90/100, with the only real flaw aside from software glitches being the weight (but it’s so nice to pull your iPad away from the keyboard so 🤷♂️)
