First of all, its sort of silly to post this question here...why would someone who wasn't getting an iphone come to a verizon iphone forum? You might as well post it over on a droid forum while you're at it - i'm sure you'll get lots of unbiased reviews.
I really like my droid x....but the fact that it is so unrefined drove me to an iphone.
1- Google search frequently freezes the phone for 90 seconds at a time. This probably happens 2 out of every 3 times I try to do a search. It's been a known issue with Froyo for months now.
2- I often-times completely lose data. The only way around it is to switch into airplane mode then back out again. Another known issue with the phone from day 1.
3- To get decent voicemail you have to use a 3rd party app (google voice), and even then I sometoimes don't get my voicemail notifications.
4- Voice search only works when it wants to
5- Sometimes when you think you're sending a text message to one person, it actually sends it to the wrong one. This has been a major and known issue for sometime...covered extensively on engadget.
6- The bloatware is flat out annoying. Do they really think that I'm going to pay $5 to rent a blockbuster movie on my phone?
7- HDMI output is a complete joke. Only works in the gallery. There is an app to make it output from other places, but the output is small and crappy.
9- LACK OF ACCESSORIES! Can you find a boombox dock for a droid? Nope. You really can't find much at all.
I concede the my Droid X can theoretically do more than my iphone 4, but my iphone 4 does what it's supposed to do 100% of the time, and it's why my Droid X is for sale on Ebay right now.
