Ouch...that's like the old saying: "what do you call a dentist? Answer: someone who couldn't get into medical school." Mean, mean, mean! 
I think each classroom now has a wireless router so you don't have to stand in line with your USB drive anymore.
Here Are Some Reasons to have a Laptop on Saba (in no particular order): 1.) Shipping a desktop computer to and from the carribbean is an excellent way to break one - I'd rather carry my little laptop on the plane. That way, I can watch "Pirates of the Caribbean: Dead Man's Chest" instead of the airline censored version of "Over the Hedge"
2a.) Saba is steep. I wouldn't want to carry anymore than is necessary to and from an apartment, which is usually up or down stairs and on a steep hill. Even if I only had to do it once, it would be a pain to lug a desktop in and out of my cottage, and try to cram it in a taxi to get it there in the first place.
2b) Less is more on Saba - don't believe me now? You will in 5th semester when you are preparing to leave the island...and it costs $200 to ship a standard 3 cubic foot box home. Of course, someone here will gladly buy your $1,000 desktop for $100 so you don't have to ship it home.
2c) Don't forget you will be traveling a lot in the next four years (to saba, home on breaks, to clinicals wherever all over the place in the U.S., running around interviewing for the Match, etc.
2d.) You want to be able to have all your basic sciences notes easily on hand where-ever you are so you can study whenever you have any free time for the step 1. Your laptop can hold all your notes, and many scanned books, etc that are available. Many times I suddenly think "What nerve innervates the subscapular muscle?" or "What anesthesia is used for endoscopy?" - and with my laptop I can look it up fast - no matter where I am. This also makes me appear partially intelligent to questioning professors, who have already gotten the wrong answer from two classmates while I looked it up.
3.) Despite the fact that Saba is a relatively crime-free island, I wouldn't feel good about going home on break and leaving my computer here. My laptop with my personal data on it goes everywhere I go.
4.) I can email people from the airport, especially if my flight is delayed to let my family know whats going on.
5.) Who wants to be the only person in class not exchanging scanned textbooks, study aids, quiz programs, a word for word complete transcript from last semester for that pain in the neck prof who doesn't use powerpoint (Hi third semesters!), music, photos, movies, games, etc? It can be hard to fit that all on your jumpdrive, you can get a lot on one day.
6.) When you don't know an answer to a question, and the professor is scanning the classroom for someone to call on, you can duck behind your LCD monitor. (Mine is huge...) When he doesn't see you and calls on someone else, refer to #2d above.
7.) There is Dell service here, the tech service guy flies over from St. Martin once in a while and fixes Dell laptops.
8.) Printing can get expensive here in the library at $10 for a 50 copy card. Printing out a lecture for one two-hour session of class can sometimes be 30 pages (with small but readable thumbnails). If you ship your own printer over here, you should make sure to bring enough printer cartridges or toner with you, because that stuff is either not available at all here, or available at double the U.S. retail price. Printer paper is also expensive here compared to U.S.
9.) You can use your laptop to record lectures. I do it all the time.
10.) Histology and Pathology and Microbiology pictures look a lot better in full color on your monitor than they do printed out, unless you plan on printing out the pictures real big in high resolution and using up gallons of printer cartridge ink or toner. And yes, those images all do look an awefully lot alike and, yes, some of those same images are on the test. They also look much better on your LCD screen than they do on the projector screen way up at the front of the classroom. And finally,(drum roll please)
11.) All but one or two professors provide lecture notes on Powerpoint. Most of the lectures are not available more than 5 minutes prior to class time to print out, because the professors constantly update and refine their presentations to better reflect what is important for the USMLE this year.
Feel free to use any of these reasons when talking to parents or brothers or whoever you want to buy you a laptop for Christmas. There are probably 50 more reasons others here can think of I can't remember just now.
