13 inch, brand new. really, it's 95% love. but this is what frustrates me: 2 usb ports (am using one with a powered hub). when i travel, need to figure how to connect 3 usb devices (so, i guess, a small hub). the hate? 2 thunderbolt ports...that i have no use for. i have a really small usb audio DAC for work, a usb music keyboard. and (sigh) a usb dongle. there ARE no thunderbolt keyboards, no SMALL thunderbolt audio interfaces. so...useless ports. and another small device (the hub) to carry. thunderbolt never lived up to it's promise, there are not a lot of peripherals. wish we had one more usb port (and one less thunderbolt port). is this everyone's problem? of course not, but...raise your hand if you use either (or both) thunderbolt ports (hmmm...i don't see any raised hands... )... so it goes.
