It does not have proper Bluetooth (can be used only for handsfree). For connecting to Internet from notebook, you need jailbreak and some application (I use ssh -D).
No cut & paste.
Push e-mail, calendar and contacts work great.
It’s not possible to use the phone while syncing.
SSH client works (TouchTerm works even if you don’t jailbreak)
Overall only after a few months of use. But it’s retarded and the only reason I got it was, that maybe if it’s retarded, the retarded parts will work well. Enough of crashing phones.
What I’m really looking forward to is Android-based phones, when they mature.
