We have a capsule, and did for DS as well. For me it is about practicality more than anything, as I will be able to strap bubs in the capsule before we actualley leave the house and it is one less thing to struggle with while I am fighting the other 2 into there car seats. I also have school run to do twice a day and it seems more logical to me be able to life bubs straight in and out, especially if they are sleeping. I have an attachment for my P&T and can just clip the capsule onto that.
