Get rid of some of your extra tech by making better use of the kit you currently have. You might even save some money in the process.
I made the hard decision to get rid of my iPhone and MiFi portable hotspot in favor of an HTC Evo 4G a few months ago, and I saved approximately $200 a month in mobile carrier charges. I miss the iPhone but I missed my money more so a change was necessary.
Now that the iPhone has hotspot functionality, another consolidation may be looming in the future.
