Let's see ....
Summer 2011 - Bought a Nook Color because it was the only device of its kind at the time - at least the only one I was aware of. I was looking for something I could read books on, but the eink readers didn't appeal to me. A 7" tablet did.
Thanksgiving 2011 - Bought a Nook Tablet. I'd been using a dual-boot SD card on my Color so I could read the few Kindle books on it that I had bought before I bought the device (had read those books on a laptop and my smartphone before that). When the Tablet was first released, you could trigger a menu setting on it that enabled installation of 3rd party apps on the device. Once they were installed, you could use them in the native OS instead of having to have them on a separate one. I thought it would be nice to have all my apps in one place (so to speak) so I went ahead and bought one. About a month later, that ability was disabled.
Fall 2012 - Bought an original Kindle Fire. Had had a falling out with B&N a couple of months earlier. Amazon announced that they would be updating their Fires; and since I wasn't sure I would like the new interface, I went ahead and bought one of the originals. (I had already decided that a Fire or a Nexus 7 would probably be my next device. I was not going to buy another Nook ever again.)
May 2013 - Bought 2 HD+s. My husband and I had been wanting tablets with a slightly larger screen for awhile so when B&N added the Google Play Store to their HDs and dropped the prices signigicantly, I decided to go for it. I treated myself to one for Mother's Day and my husband to one for Father's Day. Never say never.
I gave the Nook Color first to my husband and then to my best friend along with my Nook Tablet. Still have the Fire and the HD+ - use both of them on a regular basis.
In August 2010, I got the N1E for my birthday. I saw one in person and fell in love. I did tons of research and then told my husband I wanted one for my birthday. In September 2011, I got the NST. It was another birthday gift, this time from my mom. I love that reader. I gave the N1E to the kids, and it is still in constant use by all three of them. This Mother's Day, I picked up the HD. As much as I love my NST, I also love the HD, though for different reasons. I still prefer reading novels on the NST. I use the HD for cook books, knitting books, and sometimes magazines. I really really like it for all my pdf knitting patterns. I also use it for all my email now. It's easier than turning on my laptop everytime I want to check my email or Facebook. I wouldn't have bought it if they hadn't opened it up to Google Play, though.
I've never had any problems with any of my nooks. The N1E is very well made. It's been dropped numerous times (mostly by me) and still keeps going.
Thanks and fun to read other's days with their nooks.
Stretching out the Nook Color.
And trying to hold off for next gen of the Nook Glow.
As found the tablet great and all. Majority of the time just want to read.
And the Nook Color gets heavy laying in bed reading at night.
