Lenovo is a pretty decent brand.
However, for my money, I'd consider a
MacBook Air, especially for creative programs.
For the same money you can get a high-end 13" MacBook Air with a 256GB SSD, 12 hour battery and a boxed copy of Windows 7. (assuming you absolutely need to run Windows)
Plus the MacBook Air's just got a refresh, with PCIe-SSDs, Haswell ULV i5/i7 and the 12 hour batteries. The MacBook Air is also 1lb lighter and has a higher resolution display.
The only downside is that the MacBook Air doesn't have a tablet functionality, but the SSD is going to be way
waaaay faster than the conventional HDD in the Lenovo.
