I would suggest to purchase from Amazon because I did purchased from buy.com and the unit arrived DOA (2 of them). Also, If you are Canadian and want to return a merchandise back to buy.com, they will NOT refund the taxes (PST & GST)...you have to apply to the respective govt. to get that back...and for an n810 the taxes could be around $62, depending on the province you live in...this could take months.

My preference, get it from Dell.ca or Dell.com...great service, wait for it to go on sale. If you return the product, Dell will pay for it. plus dell got a phone #.
