to answer the orignial post, i work in abu dhabi and live in dubai marina and its fine.
i wouldn't want to be living any further north than al barsha but driving for 90 mins each way per day isn't great, but its totally fine, just like anything you get used to it.
if you lived in london you'd could easily spend 2 / 3 hours commuting to work from your home each morning, and that'd be in traffic or on public transport.
if you have to drive for 90mins each way in yoru own car, at highway speeds then its no big deal, traffic is only bad at either end, and to be hoenst its nothing you can't handle / don't get used to.
plus if you work in abu dhabi you can negotiate Capital Emirate salary so you could well end up getting paid more for same job as you would in Dubai.
i'd definitely consider it.
ultimately, i wouldn't want to live in abu dhabi, but i'm happy to drive through there every day for work
