So I've been lurking here since the rMB launched and have been using all of you as guinea pigs for my splendid agenda of ascertaining whether I REALLY want this machine or not.....also I'm tipsy whilst typing this, so apologies for insanity in advance. Right now I'm typing on my secondary machine, which is a Late 2010 11"MBA 1,6 intel core 2 duo with 4gigs ram. which is fine.......but kind of feeling like I want a change. Today I went to my local store (Bondi, Sydney, Aus) and played extensively with the 1.1ghz units. Ive seen many people here bitching about UI lag and general sluggishness with this machine but I just couldn't see that. So I'm curious whether it's in peoples heads....I mean rendering 4k video? NO. Clearly. But a usable machine that is up to 95% of the populations computational tasks? From what I saw today - Yes. I work in the health industry but also shoot fashion/corporate. Do i want a laptop to do hard raw retouching? no - I have a desktop for that. But as long as i can do a tethered shoot i'm fine. A bonus would be able to run photoshop and do some WB adjustments etc...which my MBA now can easily do. Anyway at the apple store I launched 5 programs at once on the rMB (safari, keynote, imovie, photos, and mail), opened multiple tabs in the browser, scrubbed through sample video footage in imovie, zoomed in and adjusted some sample images in imovie, and flicked through about 20 sample emails in mail. It did not skip a beat and launched them all within what i felt to be quicker times than even my desktop. I tried flicking through expose/launch control, turned on dock magnification and other UI animations. I simply don't see why some people here are whinging? this isn't slow to me...at all. In fact I then went to the most recent 11" MBA and IT FELT WAY SLOWER! So....can i deal with a laptop with only one port? Yes... only need USB. I would definitely prefer two, but that's it. My one and only resistance to clicking buy? - I don't know if the demo models are lying to me. Is there ANY WAY apple has optimised their display units to be better than what i could expect with a real world unit? I mean it seemed s fast as my i7 27" iMac with 16 gig ram. I suppose if i bought it and it just wasn't as good as what I experienced today then I could return it. But from reading multiple people's posts on here....i just expected this machine to be way less capable than i felt it was when using it. now I'm confused. And tipsier.
