<p>It does not take much time to adjust to OSX. It is not a completely different system. And just about all Mac users used Windows for all of their life until they switched.</p>

<p>generally, it’s cheaper to buy online, but if you buy at a store, it’s easier to do returns and repairs.</p>
<p>Make sure to try out whatever computer you’re looking at, or at least a similar model, before buying online. All manufacturers have their design idiosyncracies, which you may or may not like. For example, I don’t like Toshiba’s keyboard layout, HP’s touchpads, or IBM/Lenovo’s keyboard and plastics.</p>
<p>I have an older 2008 Macbook Pro. If I were to go back to Windows, I’m not sure what I’d buy…probably Asus, Dell Latitude, or a Thinkpad (even though I dislike the construction). From my experiences working on computers, I don’t like HP, Toshiba, Sony, anything Dell besides the Latitude, cheaper Acers, and certain Asus models.</p>
