I blame Apple (and then Samsung for copying Apple) for stealing this form factor from us.
Didn't have that one, but I did have the HTC TouchPro2 that came with Windows Mobile but was able to shoehorn a functional version of Android "Froyo" on it. Peak smartphone form factor limited by the technology of its time. Shame.
I still have my HTC touch dual and my HTC Magic in a drawer somewhere. Those were such exciting phones, coming from a Nokia.
Flashing Cyanogen Rom and custom recoveries felt so bleeding edge. Now a new phone is just an incremental update. A lot more stable and capable, bit kinda boring
Not just the hardware. I far prefer icons from that time as well. I hate the modern trend of flat icons with no details. They look like someone mashed them out after 5 minutes in Krita and then drugged their management into believing that it was a recreation of the Mona Lisa.
I was more of a Palm guy back then, but I picked up a Droid after getting sick of Palm fucking up their new OS and cheaping out on their flagships. They could have been great, but they chose to be shit because they took too many shortcuts and fought too much internally. Design/interface wise, the Pre and PalmOS were brilliant - way ahead of their time.
I had a couple Windows Mobile/Pocket PCs. They were flawed, yet awesome in their own way. Early Android was clearly better, but sadly it's become a locked down spy fest. I'd love a new real "Pocket PC".
I really would like a modern phone similar to a Danger Hiptop (aka the Sidekick) just for the actual buttons and scroll wheel and the coolness of flipping the screen open.
It's in my nightstand drawer now, plump from bad battery bloat. I ran it for 10 years as my bedside alarm clock. It ran a long gone app called NightClock.
