After much debate, I finally decided on this water bottle. It wasn't easy picking a water bottle, considering the millions to choose from. What's funny is that glass is the best choice, and there aren't many options. LifeFactory has some nice water bottles but I'm not to keen on their style (more feminine style, in my opinion) so I decided to go with a Takeya as it was the only other logical choice.
Pros:
A great looking water bottle. Very sleek, modern styling.
Drinking spout is perfect size. Bit larger than the usual, offering ease of drinking.
The cap is awesome. It's thick, rugged plastic, and is fun to 'flick' (as in spin) on or off the spout. The square-cut design of the cap makes it very easy to grip for removing, with or without wet hands.
The handle is very durable. Also, it 'appears' to be held on by the cap, but there is another ridge of glass holding it on.
Circumference is the right size for a perfect grip on the bottle - not too thick, not too thin.
Weight is just right, considering it is made of glass. It's nothing unreasonable.
The weight of the bottle is very well-balanced.
Cons:
The handle is a bit of a nuisance as first, since it gets in the way of your chin, but you learn to work around it.
The silicone wrapper attracts any type of tiny dust particle, but again nothing unreasonable. If you're a clean freak, try a different color than black.
Overall: I highly recommend this bottle. It's a very well-engineered and looks great. Among the other choices you have in glass water bottles (besides a Snapple bottle at the store) this is great choice. You won't be disappointed. Just remember, it is glass, and it isn't indestructible, so if you break it, that's your issue, and not a design flaw.

Water bottle still performing perfectly. Seal is solid. Handle is solid. Wrapper has not stretched any (my initial concern over time)... Greatest benefit of this bottle is that I find myself drinking more water than I normally would, much more.
Update - (2/22/12)
I am still using this bottle EVERY single day. What I find quite interesting is that over time, the 'dust' particles don't get attracted to the silicone as much. So while it started as a 'catch-all', nowadays the particles are almost unnoticeable.
Seal is still just as good as it was originally. Once that cap is on, I am completely confident tossing the bottle onto my bed or putting it into a backpack knowing it isn't going to leak anything. The handle is still holding up perfectly as well - I carry it around with my index finger so I put quite a bit of stress on it - absolutely zero change in it's performance.
