Ever since I was given a pager with a keyboard at Akamai I was hooked. My first keyboard phone was horrible. Made by motorola, just like the pager, but they had horribly messed up the UI and the phone wasn't usable as a phone without a headset. I think then I moved to my nokia 6800 which was an amazing phone. Great battery life and I could add my own ring tones. (It's now G's emergency cell phone, since he won't carry one.) I then moved to a nokia e70 running symbian. A we bit underpowered, but did a decent job at the time. Then t-mobile said they wouldn't allow "smartphones" on their pay as you go service, so a down graded to a Samsung t479 and fell in love with Samsung. Then I decided to take a risk and see if owning a smartphone without having a data plan made sense, and it was great. I got a Samsung Relay and I really really loved that phone. I really wish Samsung hadn't stopped supporting it (I'm a little less in love with Samsung.) I was in a bad no man's land where they had added the offline voice search, but not the ability to select which program answered the hand's free call button. I also wanted to at least consider a smartwatch (current leader is the Sony Talk SWR30) which seem to require newer android.
So I decided to get an s4 mini. This is when I bought an unlocked one from ebay, updated it to 4.4 and had it relock with no way to enter an unlock code. So I just sold that one on craigslist for what I paid for it.
I bought a second one which was the internationally factory unlocked version. It has a mild issue with the camera CCD, so I got a $50 refund and ultimately paid $105.
I just had t-mobile switch over to the differently sized sim. Thankfully this did not cause any issue with my legacy pay-as-you-go account (I asked first, but sometimes that's not enough.) It was quite smooth, however. So today is my first day officially with this new keyboard less phone!

It's also a little interesting that almost every phone I've ever gotten was used or imported or both. I'm super cheap, in general. Many of these phones were not "t-mobile" approved either. It's nice that t-mobile is being more welcoming to outside phones.
