I love my 15" but I am consolidating computers now and might need the portability. Has anyone ever made this transition and loved it? I am a little skeptical because I have both 15" MBP and a 13" Thinkpad X301. I find myself cramped on the 13" sometimes when I want to do hardcore work (papers, reading scientific articles, design work, coding). Also for some reason, I get the feeling that the 15" is just more "pro" than the 13". Haha completely shallow for noticing that but maybe someone out there has noticed the same thing? Looking for advice on the 15" to 13" transition and whether I will be regretting it down the line.
