It is a good phone with a number of pluses and a nubmer of issues. the main issues are mostly identified and may or may not get fixed. The main gps issue ticks people experiencing it off, since with the general Galaxy line having GPS problems it should have been better tested, but i has a decent workaround and you can either apply that or reset your device on the occasions when you get a situation where it doesn't work and you are ok.
the 3g download issue is even more shocking, and harms users daily, but it is likely we will see some action on that in measures of weeks, not months.
my own epirence is that the radio itself is not top notch, so if you live or work in low signal conditions you might be better off looking at the evo.
If you go into it knowing those things I would recommend the phone -- and I am one of the most strident critics of the bugs.
The fact is the screen is beautiful, an that is your main interface. Coming from years of WM I thought of android as less powerful, but Androids operating system speed and relative stability is frankly a pleasure with every single use, basic or intensive.
As with ANY big screen smartphone you will want a lot sof chargers. like one on your main floor, one in your bedroom (a cheap en is ok there) one in your office and one in your car -- again like with any smartphone.
I say go for it. Baby it and there is no restocking fee if n a couple days you make find you would prefer the slightly better reception of the evo, as that is the one issue that likely isn't going to change with wither action from sprint or users.
the 4g is great when workign well (outdoors or close to outdoors). it it compelling and completely changes browsing and viwing video streams expericnce
that leaves, say in an epic and evo decision, the issue of the keyboard. I am coming from front facing qwerty (treos) adn work a lot with text on the run. I have found for writing say 20 words the I don't use the keyboard,. but at least once daily I seriously need and use it. My one high schooler coming from rumor to touch pro to epic said he absolutely needed the slide out full keyboard in his epic/evo decsion -- yet now never uses the keyboard on his epic and uses swipe 100% of the time
