I'm very split about the Centro. I used one for a while, but after years of Symbian phones, I just couldn't get over how poor the hardware and how dated the OS were in comparison, even though having all of my old Palm OS applications on my phone was great.
Nokia's N-series had GPS, Wi-Fi, and good cameras years before that and it was hard to lose all of that; Symbian had proper multitasking, persistent storage, and Unicode support; and between native Symbian and J2ME apps, the software ecosystem wasn't half bad either.
Aesthetically, I'll always be a fan of Palm OS, but I couldn't bring myself to actually use it as a daily driver due to all of these limitations.
