If your medical school requires you to use a computer with a certain set of specifications, then you must use the type of computer required by your medical school. Do not use anything else otherwise, even if you have technical experience. Some schools can require a tablet, too.
I use the Sony Vaio Duo 13", which is over-priced and made in Japan. It has mixed reviews but overall I love the computer.
Here is a graduate student's review, in a STEM field, of the Sony Vaio Duo 13".
I switched from a Macbook Pro to this computer, and the computer is much more powerful in terms of functionality. OS Mavericks is outdated, even as the most updated operating system from Apple. OS Mavericks certainly lacks features, although the interface is nice.
1. If you value portability and need a decent battery life, get a computer with the Intel Haswell chipset.
2. If you desire a tablet, make sure to get a computer with some sort of digitizer, preferably a Wacom digitizer. There are basically two options with digitizer, Wacom or N-Trig. My computer uses an N-Trig digitzer, and N-Trig digitizers suck in general. They lack support with Adobe products and other software, and performance varies from which software you use. However, my computer performs exceptionally well in OneNote, and I can use this computer to replace paper, as a student, especially in conjunction with some sort of a scanner.
3. Consider the form-factor of the computer. My computer is a Ultrabook slider convertible tablet and I love my computer. It's like having an iPad, except bulkier, with full-featured Windows. Also, watching video on the screen in tablet mode feels just like watching TV.
4. So far there are no computers available on the market with both a Wacom digitizer and a Haswell chipset.
5. Remember if you drop money on a computer, once you spend that money, it's gone.
