Hello, first time I've ever posted on here! I'm looking for a bit of advice please as I'm not the most clued-up person when it comes to choosing hardware. I'm looking for a new laptop, and I was fairly set on one of the basic level 13" Mac Book Pro with Retina display (i.e. 2.4Ghz i5, 8gb ram). However, portability is a big concern from me as I travel around with it a lot and want something nice and light etc, so I went looking into the Mac Book Air range. I LOVE how light/thin it is etc, and after looking at the customisation options, I'm now seriously considering an 11" Air with 'maxed out' specs (i.e. 1.7Ghz i7, 8GB ram) - I'd be prepared to pay a bit extra to max out the specs on an Air to enable me to get as higher powered laptop as possible in that sized body. I probably ought to say what I use my laptop for. As well as all the usual stuff (web browsing, iTunes, email etc), I am an 'aspiring' website coder (currently teaching myself) so plan to very soon be using it to design some websites, so I'm guessing that will involve installing an IDE and a few other bits and bobs. I also use GIMP for photo editing quite a lot. I am someone who hates slow/unresponsive computers with a passion, so I don't want to buy something that is going to 'lag' when you open programs, click things etc as I've had before with clunky windows laptops. If I had my choice, I definitely want an Air because of how light and small they are, but my question is: based on my needs, will I be fine with this, or should I really be still considering a Pro? P.S. My current laptop is a Dell XPS M1330 with an Intel Core 2 Duo 2Ghz, & 2GB ram - this might be a really really stupid question, but since my current processor is 2Ghz, and the Air i7 would be 1.7Ghz, would I actually be getting a slower laptop, or does it not really work quite as simply as that? Thanks to anyone who chooses to help!!
