I love Mac's - always have. Recently bought a 24" IMAC for home...from the Apple On-line store. The Apple Stores are great to browse in but forget trying to get someone to help you. Ok, let me correct myself. The stores are great, but go at an off peak time. Otherwise be prepared to be jostled by sweaty people only there to check their gmail accounts and have 4-hour long MSN sessions with their friends.
In terms of service, Yorkdale gets a 5 but Fairview gets a 10. This is based on a recent issue i had with my Imac which caused me to go to the genius bar. Anyway, it all worked out.
I gave the store 4 stores because choice is kinda limited. Its not like you are going to buy your Mac at Best buy now...is it??
