Hi. I'm 68 years old and considering buying a rMBP laptop. I haven't used Mac since my fondly remembered PowerPC desktop in the 1990s. So I know there have been a few changes <wink>. Not all for the better? So I have some questions maybe you can answer. First of all, I'm reading that the transition from Mavericks to Yosemite brought about some unwanted consequences and not everyone is thrilled with the new iteration of OSX. Any thoughts on this? If it is true, would I be better off getting a refurbished Mac running Mavericks? Second, what do people feel about the force touch "improvement" on the track pad? Is it really useful and if so how? Is it hard to learn or difficult to avoid mistakes with the added capabilities? Right now I connect my computer with a wired connection from my ISP. I am thinking about getting my very first router. Is the Mac ecosystem basically unusable without wireless connectivity? Third, and this is more intangible...I feel that the past few years of improvements in computers on all platforms has led to an unmanageable complexity such that things may "not work right" with no traceable cause, just because of all the code (yes I am an old fart). Actually the new machines work remarkably well, for the most part, much better than my older machines, now dead and buried. What I am asking you here is, your subjective impressions of the evolution of the Mac platform and of Apple in general away from powerful tools toward consumer gadgetry? TIA for your replies. Mods, if this is in the wrong forum feel free to move it.
