I've got a 2010 13" 1.86 ghz 4 gb ram model. I find it a little underpowered. Even youtube in HD is a hassle but acceptable at best. Besides that it seems to be a decent laptop. I still think the old 2010 models were way overpriced for what you got but I needed a new laptop ASAP so I had to take the plunge. My question is should I lose around $400 for 3 months of use and upgrade to the 2011 or is the difference in daily tasks between the two negligible? I dont want to spend $400 just to watch youtube a little better.
