You're welcome for what? Advising me to waste my money on a device that doesn't work as well? Reliability...I guess you got me there oh wait, my last pc was on my desk for 9 years (I'm to this day still using the case). An Apple is no more reliable than a PC. The only difference there is that I can service my own if I want/need to. You cannot.
Oh, free updates? Really? That's a feature? That's pretty rich. Microsoft Windows operating systems are generally around for 12-15 years, and are updated freely for the entire duration of their existence. I'm really not sure how this is any different.
Oh and by the way, Windows 8.1 is actually an extraordinary operating system. It's probably 2x more efficient than iOS AND will run on any hardware. I promise you that if you are playing a game on your MacBook and I'm on my machine, I'll get at least 2 and probably 3x your frame rate and I promise that you paid at least $1000.00 more than I did. (I know people that play the same game as me on a new Mac...they have to reduce their settings and they still do not compare).
More and more you seem like a person who cannot see the forest for the trees. You have not provided a single shred of evidence that your MacBook will out perform a PC (including your precious battery). Please review the following article:
Apple MacBook Pro 2013 vs Dell XPS 15 2013 | News | TechRadar
and for 2014:

In both cases the Dell outperformed the MacBook in Battery life, weight and graphics. Oh, and Dell is by no means a premium manufacturer. There's better out there which will easily beat the Dell's. Apple is middle of the road at best for a premium price.
