Seriously, who cares? I can't imagine sharing a 3G connection with even 3 devices... Let alone 5.
I currently use a Verizon MiFi and I am absolutely not going to JB my iPhone (BTDT). I have used 5 connections on my MiFi at once, but I almost never "actively use" them at the same time. A typical scenario is as follows:
I often work from my beach condo... and there is no way to get broadband internet access. When we arrive, I set up my mobile office, and my personal gear.
1) Lenovo X201 (work computer)
2) 11.6" MBA (personal laptop)
3) 13.3" MBA (wife's laptop)
4) 32 GB iPad (wife's iPad)
5) 64 GB iPad (my iPad)
Personally, I am only ever using one of my 3 devices (X201, MBA, iPad) at any given time... and likewise my wife is using only one of hers (MBA, iPad) simultaneously. Of course more bandwidth is always better... however, it is useful to keep all of the devices connected, synchronizing mail, or whatever is needed. Mostly they are idle... but they are still staying in sync.
I can still accomplish the same thing using USB and BT tethering in conjunction with WiFi hotspot usage... but is is a less elegant solution.
I just checked my bandwidth. My iPhone has never gone over 1GB in any month. I typically use about 350 MB of MiFi BW per day, but I generally use it fewer than 6 days/month... so I have never gone over 2GB in a month.
Hence... I am currently paying $30 iPhone + $60 MiFi or $90/month. My new bill will be $45/month. It is worth it for me to switch.
