Hey how are ya'll?

Well after numerous threads and posts by me about building a computer or getting a new laptop or getting a good smartphone, of which I have done none until now, I decided to get a Macbook Pro, and now I have one.
Typing from it now. It's actually amazing, I'm not an avid mac fan but to finally have some good kit is nice. I think that it was definitely worth it, although I don't think I would have bought one had I not had a student discount where I got more than £400 pounds off.....I just need to get used to it now as I've been a windows user for a long while.

Just wondering if anyone knows how to boot to an external hdd. I'm gonna get an encasing for old laptops hdd and use it externally, but will I be able to run windows from it?? It'd be cool if I could, but if I can't that's also fine.

Now specosificats:

15-inch screen
2.4GHz quad-core Intel Core i7
4GB 1333MHz
750GB HDD 5400-rpm
Intel HD Graphics 3000
AMD Radeon HD 6770M with 1GB GDDR5

Might eventually upgrade the hdd to a faster RPM or SSD not sure yet.

SO EXCITING
