First smartphone was a Treo 680, which I used concurrently with a Palm T|X - I'd been attached to the PalmOS platform since my teenage years when I got a hand-me-down Pilot 5000 for my birthday. Was VERY worried about the future of the platform at that point (for good reason, as it turned out), and so when I saw in a news story that there was a Garnet (PalmOS 5) emulator available for these Internet Tablet things, it caught my attention very quickly.

I ended up swapping out the T|X for a N810 with that emulator installed (I went with the N810 because I wanted the sliding keyboard, and a GPS as well while I was at it). It was a bit rough, but I managed to do okay with a few bumps here and there. Had to do a *lot* of custom work, though, and I was never quite happy with the result. It helped a lot, though, that it was based on a Debian-ish infrastructure, as I'd been running Debian on all servers I was responsible for (and as a desktop OS, for a while!) for several years.

Then the N900 came along, and I rushed to ensure that I would no longer need to carry along chargers for and keep track of the battery level for two devices. It turned out to be better than I could have dreamed - half to two-thirds of the stuff I'd hacked into or wanted to hack into the N810's UI were already present in the N900, and the rest was extremely easy to add. My sole complaint was (and continues to be) the kickstand; the N810's was SO much better... but oh well.

I've stuck by my N900 for about three and a half years now and I'm not about to leave it.
