I used the I1000+ for several years and was afraid the I90 would be too small for a me. Wrong!. This is a rugged, yet nice piece of communication equipment. I say commo equipment, because the sales feature here is the Nextel &quot;radio&quot;. If you have family members, clients or co-workers that utilize Nextel, then this is the way to go. I have had great cell and radio coverage throughout most of Florida. I've used the cell phone in several other states as well. Nextel indicates the radio service will be nationwide next year. This phone/radio is the way to go.
