Lately it seems, more and more places that I've been going to (restaurants, Doctor's office, DMV, my work, etc. etc.) do NOT have Wifi. I just bought the Wifi only Infinity a few weeks ago and it has now replaced my beloved TF101 as my traveling companion. What I don't like about most Mifi devices and their plans is that most of the data would probably not get used up by me within the usual 30 day contract. Heck, I have the 200mg (15.00/mo) plan on my iPhone and I usually have about 50mg still leftover each month. So I obviously don't need much 3G but it's nice when wifi isn't available.
I've hesitated getting a United States coverage Mifi device, knowing that I would probably use the Mifi data only in those rare occasions where there is no Wifi available. Most of the data would be wasted. However, the other day I was snooping around the electronics department at Walmart and saw their Mifi device called "Internet On The Go". The Mifi device itself was selling for $99 (cheaper than online where it is $119). Forgive me if I'm not upto snuff on the other mifi plans out there, but the Walmart plan that goes along with their device is just what I am looking for. There is no monthly fee and the data you buy NEVER expires as long as you log onto it at least once a year. (Well, I guess it would eventually expire each year you log on, but technically it could sure last a long time!)
The Data for example: $10 for 100MB, $25 for 500MB, $45 for 1 GB may seem a little pricey. However, it doesn't expire after 30 days but only until after you use every drop of it and at YOUR own pace instead of theirs. I think this is great for the casual user like me! I have all my music on my 64GB micro, and movies (thanks to DVD Catalyst), so I don't need to stream any of that stuff while using the Mifi and actually survive a long time before I would need to buy another refill.
I went ahead and purchased the Walmart Mifi device and 500 MB to start me off. This should last me a long time. My question is are there other Mifi devices with this style of plan that's even better, so I can have buyer remorse? But for now, until someone upsets my applecart here, I think this is a pretty good idea for the casual 'out and about' Wifi only Transformer user.
