Unfortunately, by repeating the same argument over and over again about added feature as justification for the increased price, you are no better than those MyWi basher who are complaining about the price repeatedly.
Now I understand. The MyWi crybabies can pollute every thread that mentions MyWi with their immature rants, but I can't present the other side? Right. They stop whining, I stop. Don't like it, don't read the threads. Simple solution. Additionally, people are not saying MyWi is not worth it for their situation. They are whining about the price. Notice, they don't say what a fair price would be, they are just whining. People who can afford $80 or more/month and a multi-hundred dollar phone who pi$$ and moan about $20 are one step above people who steal apps on the human debris scale. I have self worth than to whine on a discussion forum about how much MyWi costs.
No where did I say the improvements justified the price. I was simply correcting yet another uninformed whiner who said there were no improvements. There are improvements. Fact.
Also, I have iTether on my iPad and TetherMe on my iPhone4 in addition to MyWi.
Only ever want to connect one device to your iPhone at a time - TetherMe - $1.99
Need to connect an iPad - iTether - $5.00 for a total of $6.99
Want an Access point to support multiple connections - MyWi - $10 upgrade/$20 new license.
EDIT: Adding to what thelatinist says below, there are tethering solutions that range from $0.00 to $20.00 ($10.00 for existing customers).
Man up or shut up.
