I know this is not what you want to hear, but I don't think a bbag would be the right bag for this purpose, unless you will consider a courier, which is not the *typical bbag* ...
My thoughts about the
work: yes, it will fit a lot of stuff, including laptop and lots of other stuff. BUT: it doesn't have a shoulder strap, just the handles. As you may have read on here, the handles may be too short to carry the bag on the shoulder, depending on the width of your arm and also on how stuffed the bag is. IMHO it is just not comfortable to carry when stuffed, esp with heavy stuff, laptop plus textbooks.
About the
city: It has a shoulder strap, but the laptop will barely fit, so the bag will look funnily square-shaped as supposed to its normal soft shape. Also, with a laptop inside, you will not be able to much more inside.
About the
part-time: this style is wider, but less high than the city, so it probably won't fit your laptop
About the
day: it will fit your laptop, but it will look square-shaped.
The
courier is the best choice IMO. The downside is that it's not a purse style, but a messenger style.
I know what I am talking about btw... I am a student also and just HAD to have a bbag. Of course I could only afford
one bbag, so I picked the city style, because I liked it best. It does not work well with a laptop. It is just too uncomfortable to carry with a laptop inside
The same applies to carrying more than one textbook... So I only ever carry my city to school when I only need a notebook, water bottle, pencil case. Also consider that when you have a bbag, you may not want to put it on the ground or carry it in the rain, since the leather is delicate. Not when it comes to ripping, just when it comes to discoloration or stains...
Don't wanna scare you off or anything, but I just thought you should know what to expect. If you can compromise, you may still wanna get a bbag... Anyway, good luck finding the perfect bag for your needs
(hope it will be a bbag in the end! )
