The Vaio Z is a pretty fast machine, especially given the SSD. I doubt if it actually takes a whole minute to boot up, probably less than 30 seconds. Windows 7 just takes a fat while of time to start, regardless of the machine it runs on.
I have a Vaio F.. it's nice for a Windows laptop, but I'd jump for a 17" MBP if I could afford it. HOWEVER, unlike the F vs MBP 17" - a fair comparison where both machines class very similarly (and the MBP wins in battery life), the 13" MBP is a little piece of crap that doesn't deserve the "Pro" name.
