i have not used a blackberry - other than casually from a friend for awhile. i -have- been using smartphones for many years, always upgrading along the palm-os line (my last one was a treo-700). i really like the os that palm has and the keyboards on the treo were always bigger than the centro for my big-fumbly-hands.
it used-to-be that the big seller with blackberry was instant-email (ie, they had a patent on the push-technology for emails - i could go into more details if you care). they are also great with outlook - and i like their keyboards. personally, i find having emails going -bing- all day into my phone annoying so i prefer to only check emails when i want to. and with other-phones using pull-technology you can have it check every 15 mins anyway.
i have just this past week (after lusting after the g1 with tmobile for a year or two - im on sprint) finally gotten a google-os powered phone. i also took this opportunity to change from a keyboard to a touchscreen-typing... i am still getting used to it - especially with my big clunky fingers... i might decide to change back to a keyboard very soon if i get too frustrated.
i agree with the others, go to a verizon store and try them out... if you have already done that and think the env3 is gonna be what you would like - then go for it... altho, you might triple-check with the actual-reason for having a phone - the phone part (lol - but i am not kidding)... my friend absolutely loves her smart-phone for everything -except- the phone !!! i have been very happy with my smartphones -particularly- for their phone capabilities, as well as the other-stuff...
once youve started using the web/email/whatever - then you might be surprised at how addictive some of the other random features will become... for instance, i never really wanted direction-for-driving; esp if i just pulled up the google-map of the address, but now i am hooked on the little voice telling me where-to-go and adjusting for the gps-current-position... (my old smartphone did not have gps)
if you -do- a lot of emails on your phone, then spend a fair amount of time typing on the display model... and opening-closing the lid or whatever... most of my time is spent actually getting-the-phone out of its case, rather than actively doing something on it... make sure it is easy to answer (phonewise) and you should be fine...
sorry to be all babbly - bottom line? it should be fine...
(urp i just googled 'verizon env3 problems' and found this http://forums.verizon.com/t5/Cell-Phone-General-Device/LG-EnV3-Problems-charging-screen-animation-wallpaper/td-p/43225/page/3 from several months ago... might not be an issue now, but it is always a good idea to google things i guess...)
exactly 8.25250000001mm (0g) ear lobes ? goal reached, but currently downsizing/healing old wounds... so that i can create -new- ones... lol...
