My one and only reservation about taking the plunge into Maemo 5:

I'm still not aware of any way to keep it sync'ed with my google contacts and/or google calendar. I don't mean with erming, I mean with the native Maemo 5 contacts and calendar. If it supported true/full SyncML, it would be a no brainer -- GooSync. But, Maemo5's SyncML support is lobotomized/castrated for some unknown reason (BT/USB only).

I might be able to do without the calendar syncing ... but not without the contacts syncing. It'd be rather annoying to not be able to directly make phone calls with a phone ... always having to look the contact up in gmail so that I can then manually dial them. That would be rather pointless. (and, google will always be the current/authoritative source of my contacts, thus Maemo5 must accommodate that, and not dictate that I make something like Ovi be the authoritative data source, nor something else equally inane).
