If you want something really good with Wi-Fi, 3G, Facebook, good 5 MP camera with video and a nice tilt screen, N97 is the solution. It will be available this month in 70 countries, including US and I believe in Canada as well.
What is good it has free facebook and twitter clients, free IM clients for YM, Windows Live Hotmail, etc., Google Maps and Nokia Maps, GPS, good webbrowser, 640x360 resolution so you can watch any site without much horizontal scroll, it has Flash so youtobe and other videos can play in the web-browser.
You can buy it now from Amazon for 599 $ (the NAM version). It will be shipped in 2 weeks. Better wait for any deal with operators so the price will go to about 199$ or less subsidized with a plan.
