Well, I finally went and did it. I coughed up for a brand new HTC Desire 610, with a flip case. The case is in the mail, but I got the phone.. and she's a beauty.
The screen is about twice as large as my old phone. It's easier to read, by far. It feels huge, but it still fits in a shirt pocket - extra bonus! Tons of apps, the latest Android, and it took my 32GB microSD card without an issue.
But.. and you knew there'd be a BUT, right? .. setting the thing up was a huge pain in the tail!
It REQUIRES a wireless connection. Where I work, the guest wireless is useless and we all have hardline connections. I literally had to walk to where my old phone could get at least 2 bars, set it up as a mobile hotspot, and use IT to get online so I could log in and set the phone up!
I wonder what happens if you're in a dead zone? Ship it back, I guess.
Anyway, after 20 minutes of cursing, my shiny new phone is actually working and seems good so far. It's just different enough to have some learning curve, so we'll see how I feel in a week or so.
I hope this thing lasts a few years...
