The Goods:
Milk - Cow's milk would probably be better, but I didn't have any on hand so I made do with the soy.
Flavor syrup - I went to Starbuck's to make sure they really don't sell their pumpkin spice syrup. They don't, so I bought vanilla instead.
Espresso maker - delivered on Friday! Yay!
illy espresso - This is supposedly the best kind to use with my particular espresso maker. It's more expensive than what I would usually buy, but if I'm going to do this I want to do it right.
Milk frother - bought from Williams-Sonoma this week because it did not qualify for Super Saver Shipping, and I wasn't going to pay $7 to have it shipped.

The Verdict:Meh.

My first attempt wasn't the best. You're not supposed to heat the water over 175 degrees or the espresso will be bitter, and my meat thermometer recently broke, so I had no way to measure the temperature of the water. I completely underestimated the water temperature, and also failed to sufficiently warm the milk, so my first latte was lukewarm at best. I also wasn't sure about the ratio of milk to espresso to syrup, and I think I guessed poorly on those as well. After drinking this tepid concoction, I was thinking that possibly this whole latte making idea was a lot more trouble than it was worth.

I attempted another one later yesterday afternoon, and it was much better.This morning, I attempted a third time. Wow. It was good. Really, really good. It tasted just like the real thing and was perfectly hot and absolutely delicious. Definitely worth the trouble. I am so looking forward to tomorrow morning so I can have another one!
