I'm what one would call a hard-core switcher. I didnt switch because I didn't like windows (rather I very much like windows), mainly because a) mac osx had some applications I really wanted (and were obviously way more innovative their windows equivalents), and b) I'm really a bit of a computer junkie when it comes down to it. I got a new macbook pro (unibody) and have spent a long time figuring out how to do everything I used to do on windows on my mac. I have downloaded, and am using the programs I wanted to try. And these programs are highly innovative, enough so to warrant buying the mac simply for that reason, so overall, Im still really happy with the purchase. And quite frankly, its the prettiest computer I've ever owned. But heres what I find: it's just slower. Perhaps not for all operations, but for operations I depend on for work purposes, its like a third as fast, a) opening office documents (I've tried several office packages), b) using matlab, c) switching between many applications at once to get a task completed, d) opening applications and documents in general, e) memory things that cause the pinwheel to make me take a 5 second break quite often. f) despite what apple had me believing, programs don't just always work. In fact, my experience is that they dysfunction more often than windows ones and need to be forced quit! These things just make it impossible to get things done. Am I missing out here somehow or missing something huge? On my PC, I almost never have to wait for anything. Despite the myth of windows getting sluggish, or that has issues, my windows XP system (which has far few components than my new macbook pro), does things more or less instaneously and has not gotten slower over time. In windows I have control over what services and processes it runs so the system doesnt get bogged down by things I don't use, making an overall more responsive system. My mac osx system commonly feels like its trying to do everything at once and struggles to get through some of the most basic tasks. Perhaps anyone else has a common experience? MY hope is really that snow leopard makes the system overall more pleasant to use.
