Dear all, I am considering two similarly priced scenarios The weight of my 15" 2009 Macbook Pro has started to become tiresome. I really want to have a portable computer for doing casual work but still have processing power when I need it at home. I'm very interested in the newly released Macbook Air (13" inch i7 8GB ram + 256gb storage) and want to buy it to replace my Macbook Pro. It's lower weight would make it much easier to carry around, it's processing speed is faster, and the GPU processing slightly faster (HD 4000 vs 9600m GT according to notebookcheck comparison). The hard drive space is limited though, but can be manageable. However, from checking refurb.me, I found out that the Hong Kong apple store have 2010 macbook airs in stock for approximately $772 US for the 11" 2010 4GB 128Gb model, which is enough when I'm on the go. It also would mean that I don't have to compromise on the screen size, since I can use a larger screen when I'm at home and still remain very portable outside. I can also upgrade my older Macbook Pro with a larger hard drive and more ram in the future, keeping it up to date. I occasionally like to play games such as Skyrim and Starcraft 2, and do a lot of amateur video production when I'm at home. I also carry a computer with me whenever I'm on the go for lectures and for projects. I'm faced these choices, both results in similar amounts of money (selling for $876 - $1608 = $732 vs - $772). Option 1: Selling macbook pro and replacing with an ultimate Macbook Air (13", i7, 8gb ram, 256 hd): Advantage: Centralized storage and work Performance available everywhere I go. Faster storage and more Ram than Macbook pro USB 3.0 and Thunderbolt More future proof for using and selling Disadvantage: Hard drive space will be limited, from 500 gb to 256 gb for my primary computer (Wants to run bootcamp, External storage a hassle, multimedia editing hampered) Feeling of spending a lot of cash just for the storage upgrade (Very inefficient) Selling hassle Speakers Compromising on portability May have to get an external dvd drive if I need to burn something Option 2: Buying the cheapest macbook air to compensate for traveling: Advantage: More portable for 11" Macbook air More storage on 15" Macbook Pro Don't have to bother with selling the 15" Macbook Pro Can still keep my CD drive (hardly use it though). Flexible on options, can cost less at US $665 or more for storage/speed 2 Computers instead of one. (Not sure how useful that is) Better speakers when working on primary computer Ram upgradability on 15" Macbook Pro Disadvantage: File/Work management will be a little more of a hassle (Like browsing session or running programs) Performance related tasks limited to Macbook Pro, Slower Hard drive on primary computer Lacking USB 3.0 for both computers, thunderbolt for primary computer Selling the computers in the future will be even more difficult. Is there anything else that I'm not considering, and what would you think is a good idea? I hope the writing's not too long but I've been thinking about this for some time. One option is to get a computer that have satisfactory compromises while the other is primarily augmenting my computing mobility. I think either option can be useful for different people and would like to share and discuss.
