Hi all Many thanks in advance for any help. My current Asus laptop has died on me after 2 years (typically all my laptops last me 2 years). I have always had Windows laptops in the past. I have an iphone and an ipad which is why I'm now looking to Apple for my next laptop. However, I'm finding trying to decide which spec I need a nightmare. I'm looking at the new MacBook Pro retina model which has just come out. Requirements as follows: - On the whole, I have my laptop on all evening every evening and all day weekends. - I usually have at least 4-5 browser tabs open at a time (eg always have facebook and twitter open in the background, then may be actively looking at at least another 2 pages at once). I also usually keep my mailbox open. - I take a lot of large photos (18 megapixels a time) and use photo-editing software photoshop and lightroom (open the same time as all my browser windows) - I dont do any video editing or serious gaming. I dont do any programming or web development or anything. My main usage is internet browsing and photography. - I have a lot of music but currently signed up to itunes match which keeps it in the cloud. - My current laptop screen is 15 inches. I have an ipad for on-the-move, I dont really take my laptop out and about (possibly just because its too bulky). I feel like it could be a bit of a shock going down to 13 inches and possibly not the best for the photography. However the 15 inch models are ridiculously expensive. Its my understanding the newest OS will require quite a lot of memory. Any help gratefully received. Id be looking at the new mackbook pro retina models which came out last week. Customising them is possible, but Im leaning towards buying from John Lewis and getting 5 year warranty which would mean Id have to stick to the pre-configured models.
