Recently active questions in Timbuk2 about Track Day Pack

I need a new backpack for school and am having trouble deciding between the commute and track daypacks. I would rather not have an excessively large bag, would the commute suffice for carrying a laptop with a few books/notebooks and maybe a spare layer or is something a little bigger going to be necessary?

I bought a ballistic nylon Track daypack about a year ago and the handle is tearing off. This is a lightly used bag and the rest of the bag almost looks like new. Is this normal?

What are the differences between the Original and the Newer Track Daypack?

All I notice is there seems to be an extra compartment in the newer one. Could someone provide the dimensions of the Original Track Daypack?

Thanks!

Are there dedicated locations for cables and power adapter in the Track and Commute Daypacks?

It'd be GREAT if there were dedicated compartments for them instead of just having the charger thrown in with the rest of the stuff in the daypack.

Is the track day pack coming in other colors soon?

Does the Track Day Pack laptop bag have a waterproof rubber bottom? I know it says so on the site, but when I was looking at a Track Day Pack in a local store, it had a normal bottom. Also, in some of the pictures of the Track Day Pack, it's hard to tell whether it has a waterproof rubber bottom.

I was also wondering how resistant to rain the Track is. I currently have a messenger bag and I love the rubber waterproof flap but my next bag will be a backpack that has to be able to resist rain for at most 15 minutes (my morning walk commute) with a laptop in it. Any other recommendations if the Track isn't best suited for rain?

Thanks!

Will it hold up to heavy rain?
The zipper does seem to have some sort of protection, but is it enough?

I travel a lot, and i am looking for a good backpack that will protect my laptop (compaq presario f500) and while also doubling as a good carry-on. I'm wondering which is a better choice - the track daypack or the undergound? I'll also be using the bag on long walks for carrying groceries and such.
