Hi guys, As of now I have a 2007 15" MBP and a 2011 21.5" iMac. I was planning on keeping both computers and purchasing an iPad 3. However, I have come to the conclusion that as much as I want the new iPad, it makes no sense to spend an awful lot of money on the iPad, when my 5-year old computer needs a replacement badly, as it has a battery which lasts 1-2 hours and could die any day (nVidia graphics). Moreover, I will probably start university this autumn, hence a new computer would be great. I was planning on waiting for the new Ivy Bridge 15" MacBook Air, as I love the portability of the Air, but would prefer the larger 15" screen of my MBP. I figured that the 15" Air would be perfect for me. However, today I got the opportunity to purchase a brand new in box, never opened 13.3" MacBook Air for $700. This is the latest model with the i5 processor, 4GB RAM and 128GB SSD. The seller claims he got this computer from his work, however he already has a laptop which he is happy with, hence the decides to sell this MBA. While the price does seem very low, the seller is able to provide me with a copy of the receipt from the original purchase. The computer is still under warranty, and as said previously, brand new in box, never opened. I really like the MacBook Air. The portability suits me perfectly, and the performance should be sufficient. Mind you, I only use my computer for the usual stuff; web-browsing, listening to music, photos (basic editing perhaps), word-processing and very seldom some movie editing. I purchased the MBP thinking that I would also use it to play games, however I soon realized that laptops get too warm for gaming, instead I play games on my consoles. The only drawback I can see with the MBA is the limited amount of disk space. I can do without the ODD. For the price however, I don't think I can go wrong with this MBA. Furthermore, I have my iMac for the heavy tasks. As of now, I will meet the seller tomorrow and purchase the computer. No matter how much I want the 15" Air, I do realize that it will cost me at least twice as much money, which I find hard to justify. The price of this MBA is very attractive. What do you guys think? Also, am I able to check the serial number in order to make sure the computer is not stolen, or missing? The seller seems serious, but I guess you can never be too suspicious when purchasing brand new MacBook Air for nearly half the price. Thanks in advance!
