If you will put all of the options of the phone to use and don't need any extras right now...this phone is KICK ARSE!!! Sure there are some glitches but I think most of them are software/firmware related and can be worked out. For a 1st Gen product it really does what the commercials said it would.
I had my mind set to get one...then read some of the Apple bashers (I am a PC user myself) comments and thought twice...but I just came to the conclusion that....I don't care...if it is a piece of crap, we will get our money back... No company as big as Apple could put a broken product on the market and live to get away with it for long...and it just looked so cool...it does everything I want it to.
On the other hand, I would love to buy my girlfriend one, but she is Chinese and writes and reads a lot of Chinese newspapers, books, blogs, etc. on her current phone which she purchased from Hong Kong and transferred over to the States...although she would think it a really cool phone, she would miss a lot of the cool games and other features on her phone because, well, on her phone, she can type in Chinese...
Deciding on whether or not to crack open that box depends on two things...will you use it for more than just a phone? and do you need less than a traditional PDA Phone (treo, Q, blackberry)? If you fall anywhere between, take a deep breath and join us...you won't regret it.
