Hi guys, I'm currently in the market for a new laptop for my mom after her hand-me-down 15" PowerBook G4 died. I have a friend who works for an Apple Authorized Reseller, and I've been offered a special deal on either a brand new Rev B MacBook Air 1.6GHz with 128GB SSD (a CTO model which they had in stock but didn't sell), or the Rev B 1.86/SSD model for US$200 more. To put the price difference into perspective, since I'm in Australia: the 1.6/SSD model costs the same as a new white 2.13 MacBook, while the 1.86/SSD model costs slightly more than a 13" 2.26 MBP. The 1.6/SSD is very tempting, and should handle everything my mum will throw at it, with one possible exception: HD video playback. This is of some concern, since a search of these forums shows many MBA users -- particularly those with 1.6 MBAs -- having playback/heat/fan issues with HD content, such as YouTube HD. Many of those posts are also a few months old. Has HD video and Flash performance improved significantly with Snow Leopard? Can the 1.6/SSD models handle such content better now? Would there be much difference in overall performance between the 1.6/SSD and 1.86/SSD? Would the 1.86 handle HD content appreciably better than the 1.6? Are the performance gains to be had with the 1.86 worth the extra $200 (i.e. a 20% premium)? (If I *had* to pay $200 more, the 13" MBP would also come into consideration, since the extra portability of the MBA is desirable but not essential.) Any help would be much appreciated!
