In a search for Core 2nd and 3rd Generation Laptop under 2.5KG with hybrid HDD or SSD (that pretty much summarizes the Ultrabook category these days) I was interested to see the Lenovo Thinkpad E130 show up as the cheapest Ivy Bridge option on the market. €541. I had to double check but sure enough, there’s a hybrid SSD inside which shows what effect the Ultrabook is having on the mainstream laptop market. Why isn’t it an Ultrabook? It’s 23mm thick, 5mm over the maximum thickness for an Ultrabook. There’s a good reason for that and it might just be what you’re looking for.
