Thinking about moving to Macbooks (again) and I'd appreciate some advice. Though I've owned and used Apple devices (over the past 25 years...), still do, and lurk on this forum, the killer for me switching from Thinkpad to Mac for my daily workhorse laptop is the Wifi. Recently I got a great deal on a 13 inch 2013 rMBP from a mate who fixes Macs in London (HampsteadMac, if I am allowed a plug). The next morning, after I said it was not the right laptop for me, he offered me a refund, which I immediately accepted, for one reason: poor WiFi. It had a clean install of the OS, and it worked fine in the same room as a good router. However, if you also like to connect in cafes, hotels and airports that is missing the point. My little Thinkpad x220 with Windows (or Linux), though nothing special, is far better than the rMBP at getting a signal, and staying connected, on a poor quality WiFi. So I have one question, ahead of trying again to make the jump: have Apple improved WiFi performance on recent rMBPs, or on the new MB, since the 2013 model I tried? Or is the Air better? If I buy a newer Mac laptop, can I expect it to match something like my x220 for performance on poor quality WiFi? Or are Apple still painfully behind the competition, when it comes to connecting to distant, non-Apple routers?
