I'm using the 9800 since the day of release, here in the US. Granted, quality of the release-day phones was a bit below par (slider wiggles, my speaker on the phone conked out after 1.5 months), but the phone itself is my business heaven.
All the inboxes i need, within one press of a key to monitor when getting off planes, or keeping up to speed right before boarding. Texting easier than ever before. Browser is amazing, finally up to par with current technologies.
The release-day firmware / rom contained a number of bugs. But thanks to sites the likes of crackberry, new roms were leaked and made public days after launch. It fixed most of the gripes, such as a tinny buzz over the earphones while speaking, volume level of the phone in general, and some other issues.
Battery life is excellent -- almost two days of intensive calling / browsing / emailing.
Of course, AT&T as the only provider for me is not a good thing. Being on the West Coast a lot does mean poor reception / data speeds. Dropped calls galore, close to Los Angeles.
Pry it from my dead cold hands, is all I have to say. And you know what else? No fart apps.
