Hello, My 2008 iMac finally failed me. Been a good 8 years haha. I have been using my 2010 MBP (2.4 ghz, 4 gb ram) and am wondering how much longer it'll last. So now I'm considering upgrading to a new MBP or MacBook Air. I don't like the new MacBook. I really like the desktop feel, so this will be connected to an external display most of the time. I haven't figured out what kind of display yet but possibly a 34 inch ultrawide. As far as my usage, nothing all that intensive- browsing the Internet, YouTube, word processing, (Spotify maybe). I won't be editing video or pictures. I just want it to be snappy as my current MBP is a little laggy when performing normal tasks (copying and pasting to name one). So I'm kind of at an impasse. Do I upgrade to 8gb ram for $50 even though my HDD is rpm? Is it even worth it to buy a MacBook Air anymore? Any help for this casual user is appreciated. Thanks.
