Hi All, I am about to buy my first Mac ever –Macbook Air. The spec should be: 13”, 4GB RAM, 256GB SSD and I was thinking about the i5 Processor... However the reported here on the forum heat issue are putting me off now. Not that I am worrying about the processor itself, but a hot laptop on my lap with possibly a hot keyboard I could live without the backlit keyboard (never had one), the Tunderbolt would be nice – but is not a must have. The main questions are: -In everyday use (Internet browsing, running local wamp server for design of Joomla and Drupal websites, CS5) is there a much difference between them to (2010 vs 2011)? -Will be the OS smooth and responsive enough on 2010 ultimate? -Will the 2010 run much cooler than the 2011 i5? (or is the heat issue on 13 i5 not that bad?) -Is the battery life the same on 2010 and 2011 i5? This topic is not about saving the money – just buying a better laptop. Thanks Jake.
