My 2011 MacBook Pro has a broken keyboard and there's a faint line going across the bottom of the screen, and the 2010 I'm using right now has the discrete GPU problem, So I'm not very happy with either of them. I admit that if I had some decent cash to throw on a good monitor that the 2011 wouldn't be all that bad (it's hooked up to a subpar Dell in the living room at the moment), was lucky that the 2010 was sent to spend the rest of its life in a closet. The performance of both aren't bad otherwise, I thought the 2011 was actually worse in the beginning because I had so many issues in OS X Lion that ML fixed. Mavericks was even better, Yosemite was bad because of the Helvetica Neue font that looked terrible, but San Francisco has been great on El Capitan. Really, really, really am looking forward to the new MacBook Pros.
iPad Mini, 1st gen - The App Store constantly never loads anymore, I sometimes notice ghosting, and performance in general is very hit and miss. It's still perfectly fine to type on, read ebooks, watch video, and play games on. But I don't think I'm replacing it with another one. At the beginning with iOS 6 it was great though and I've put lots and lots of miles on it.
iPod Touch, 5th gen - Just got done listening to some podcasts on it. It's using the same old tech as the iPad Mini, but I only use it for audio so it really doesn't matter. I'm still pretty happy with it.
iPhone 6S Plus - Good - I like the 3D Touch features - I use peek and pop a lot, and I have all my keys in Nintype to do different things when you force touch them, my favorite being copy and paste which I have set to the C and V keys. The camera is great, and Night Shift has been really nice!
I had two Android phones between 2012-2013. Yeah, there is a lot more they do in comparison to iOS. What left a bad taste in my mouth was a messed up Google Play update that caused the phone to lockup to the point that I couldn't unlock it. Google probably handles updates a lot better these days, but I'm just not that interested anymore. The Lumia 520 I had afterwards was more enjoyable and was the last time I actually got excited over a piece of tech, but at the end of the day I just got another iPhone.
