Hi guys, I'm going to buy a new 15 rMBP in September. I know that perhaps new skylake will be introduced in October, but I need the new macbook as soon as apossible and I think the actual 15 rMBP is a great machine for me. My last MBP is from 2009 and I hope this new rMPB stays with me 5-6 years too. I'll use my rMBP 99% for work: web development (Magento, Rails, virtual machines, etc), office and Photoshop (No video edition and no games) I'm going to buy a new external monitor too (my old monitor dies two months ago). I don't discard to acquire two monitors, perhaps not at the same time but i don't discard to acquire additional monitor to work with two monitors with my laptop closed in future. I have some doubts in this way, last moth I have been reading about external display and these are my actual options: U2415: This 24" with 1920x1080 16:10 seems great for me. Ok It's no 2k-4k monitor but actually, for web development, this resolution is enough. Some people has connected this monitor with HDMI cable to the new 15 rMBP perfectly but my problem appears if I need a second monitor, I think there's no possibility to use two u2415 with new rMBP 15" 2015 (display port problems) http://www.amazon.es/DELL-UltraShar...?ie=UTF8&qid=1439127961&sr=8-1&keywords=u2415 U2415H: 16:9 2560 x 1440. I prefer 16:10 but if there's no problem to use two of this monitors with 2015 rMBP it would be a great option too. http://www.amazon.es/Dell-U2515H-pu...?ie=UTF8&qid=1439127961&sr=8-3&keywords=u2415 P2415Q: It's a 4k monitor, It would be my last option initially, is more expensive and I think I’ll work better with two different monitors with less resolution that with only one 4k monitor (two P2415Q is not an option, too much expensive for me). http://www.amazon.es/DELL-UltraShar...ie=UTF8&qid=1439128174&sr=8-1&keywords=dell+q Obviously I want to acquire one/two monitors for a long time. Like you can see, I think 24" is enough for me. If you have experience in these monitors and you have a pair of these connected to yours rMBP it would be nice know your impressions.
