1) I really hate the hardware upsell. With this XPS machine I'm getting a 256gb SSD, 8G RAM, and an 3GHz i7 processor. The comparable hardware for a 13" Retina is $2,200 and it's still not as light or thin. The comparable Air is missing a GHz of processing speed and still costs an extra $150. Also, there isn't a team of OEM Apple developers writing Ubuntu PPA support for either machine, so I'm stuck on OS X again, which I'm pretty disillusioned with.
2) I'm actually still not really clear what the advantage of a retina display is. Maybe it's because I haven't been able to use one for a significant timespan, but I just don't get it. If there was a way to clearly and easily illustrate why a 13" display benefits from retina resolution, I'd really appreciate it.
3) I'm kind've ready for a change from Apple products. I haven't used a high end laptop or PC from any other manufacturer and I feel like I don't know what I'm missing, if I'm missing anything.
If you or the other XPS tester can respond at all, thanks in advance.
