Mac users are running a pretty marginal OS, when all is said and done. What is it, 4% market share for Apple atm? Being a Mac user, I can imagine that it is not fun to acknowledge the fact that supporting those 4%, of which a small sub-percentage may be candidates for buying a 770, is of rather limited importance to Nokia. Certainly focusing on Windows first and possibly Linux support second for the tools makes perfect sense, with Mac support added later as an afterthought, time permitting.

As for support experiences... well, in my opinion, the quality of the support you get for consumer products seems to be invariably crappy these days. Pro stuff that costs a minor fortune and where you have to pay through the nose for support gets great support because it is a life or death thing for the company, but the $360 you paid doesn't include a lot of leeway for providing premium support.

Personally I practically never even try to get support for a consumer level device unless it is actually broken and I need some warranty attention - the people answering the phones will most likely be named Sandeep or something like that and sit somewhere in a support outsourcing center in India with a script to read and follow when users call and want support... :P
