"As someone who doesn't reside in the USA, I was wondering what would be the best way to get internet for my computer in the US for a couple of weeks? If it were Europe I know I'd look for some prepaid data. Is there anything similar offered by American carriers? A MiFi or a data SIM that I can tether from would work, but I'm trying to maintain a tight budget. Help!"
I've been really happy with my Netflix BD rentals. I must live in an area that doesn't have many BD renters. There's be a couple of short delays but no more so than DVD rentals of the same movies. I have about a three day turn around. It's certainly worth the extra buck. Saved me from buying some real turkeys.
