The OS is standard bullet-proof RIM quality.
The phone feels nice and weighty and solid.
The screen is beautiful.
The sound quality is great as I have yet to go past half volume.
The keyboard works great (even with meaty fingers when you get used to it)

The rails are the ONLY downfall of this phone to me and the FIRST time I have ever questioned the build quality of a RIM product and this is exactly how I stated it to RIM. I personally think it can be resolved with aftermarket rails and if so (and can be done for less than $20) I am still stoked about this phone.

My main concern was if the sides are this loose and squeaky during the first week of use what will 2 years of under contract with this phone be like...

Hopefully RIM or a 3P will come up with a solution to this minor but VERY annoying issue.
