Get MBA or iPad?

[cramazing]

So I have this Lenovo T430s for work, it has great specs, but the graphics on it is just terrible, especially since I have a 15" Retina display MBP for personally use.

I am now debating if I should sell the Lenovo and either get a 11" or 13" Macbook Air or the new gen iPad. The machine I use for work will mostly be for Outlook, and maybe some MS Office stuff, but mostly for Outlook. I dont carry this machine to work as I have a desktop in the office, this device mainly stays at home, and once in a while to a business meeting or when I travel.

The reason I got the Lenovo was to learn Windows 8 a little bit and also have both Mac and Windows machines at home, but after 2 months of use, the Lenovo is just undesirable.

Here's my spec on the Lenovo.
