I got an Upstage phone.. I don't know about KRZR... sounds like an Motorala phone.... Upstage is really target towards younger people, not for business.. So if you're a business type of person, this phone is not for you... Also this phone is kinda easy to lose... I lost it in a Galleria and some called my house and told me to come pick it up at Macy's! :) Anyway, other then that it is a good phone.. It is like an regular phone... with an MP3 side... If you can handle an iPod, you can handle an Upstage! Also, if you go to Sprint, ask for an extended battery case! Because with that, you can leave your phone uncharged to four to five days! (I've tried it) Without that case, you'll be lucky if it lasts three days!

'im not sure about the krzr and how bad you would want it, but the upstage is brilliant if you're going to use it for its media capabilities, but if you're not then its going to be sort of impractical to use. my brother has one, he loves it but finds it tedious at times. if your looking for another sprint music phone, then the m1 is a pretty good option, although cost-wise its not the best. the fusic is also a pretty good music phone. although you mite want to wait for the newer version of it, the musiq which is slicker and i think it holds more memory also.
