As above, its starting to get sluggish recently and the battery is not what it used to be. Its the base model with 4GB Ram and 128GB SSD. I mainly use my current model at home but I do need it sometimes when out and about. I make (attempt) music in my spare time so using the 13" is to small so I have a budget 24" Acer monitor (1080p) that I use as a second screen. I also sell quite a large amount of items on eBay (vintage items) so its nice to have a few windows open for Garagesale, Lightroom and Safari for looking up items etc. I also very occasionally use my iPad using the Duet for a tethered 3rd display but I hardy use it now after getting the 2nd monitor: I have a iPad Air 2 which again, is from my late mother (I bought it for her about a year ago and I think she used it twice the whole time!) which I hardly use. It was also such a nightmare getting the iCloud turned off so it so I could set it up under my one. Apple were extremely unhelpful in that matter. They wanted a letter from the courts stating it was my property etc but I got there in the end by reconnecting her Vodafone contract with the same number for a month to get the access code for her hotmail which was her backup for her iCloud as I didn't know her passwords etc. So carrying on, I hardly use the iPad but I might make use of it a lot more as a central hub for HomeKit/HomeBridge appliances as I start to get more smart things setup, so I think I might keep it for now. So I figure the options are based on a budget of around £2000: Buy the new 27" iMac base (£1749) and keep my old 13" MacBook Pro but have the battery changed (£199). Total £1949 Buy the new top 13" MacBook Pro Touch Bar (£1749), LG UltraFine 4K Display (£629), already have the Magic Mouse 2 and Magic Keyboard and sell my 13" MacBook Pro (around £400). Total: £1978 Buy the new top 15" MacBook Pro Touch Bar (£2,349.00), keep the display I have and sell my old 13" MacBook Pro (around £400). Total : £1949 Opinions or other options? As I mentioned before, I just really need two nice screens with some portability. I don't use them for playing games.
