It could be but I'm not sure about the 5 hour battery life. I'm not sure whether I should get this or the t100 that has double the battery life but no android.

Research.

If you are a student then you really won't need Android OS. Unless you wanted to use it to play mobile games for killing time. Not only that but we don't know how the Duet will perform in real world use. Plus its won't be coming out soon. According to Engadget, it suppose to come late 1Q in Europe and Asia and late 2Q in the state. So you will have to wait if you decide to get the Duet.

The T100 has strong battery life but some weak specs. So it not made to do anything heavy on it. Not I read some complaints about the keyboard

Between just those two I would wait or look for a different product. For the duet the top tier spec will be cost just as much as an Ultrabook($1000+). While the T100 is cheap on one hand but as a student you will want that will last a while.

From the looks of it you would need an external cd/dvd drive for both devices if your courses/classes require to you to use a disc to complete certain assignments. Carrying around one of those can become a pain.

I would buy an good full size/regular laptop. If I wanted a tablet for times when I don't want to pop out the laptop, then I would buy an cheap android tablet(Nexus 7(1st gen) or HiSense Sero 7 Pro) along with it. I've seen the first gen Nexus 7 32gb for $150 or less, quite a few times. The HiSense Sero 7 pro has similar specs to that of the Nexus 7. I've seen it cheap as $89 at times. On the downside it only has 8gb but it has a microsd slot.

Also more than likely you would buy a new laptop 2-3years(at least) or 3-4years(if you're lucky). Mainly because you will want something stronger or the laptop you used became worn down over time.

I had my laptop for the last 4yrs and used it for gaming and school. The battery now can only last about a good 5minutes before dying without the charger. The first charger ended up dying out on me and I went through three universal chargers. The screen got some dead pixels. The fan has become louder and the laptop itself gets hot fast. I had to rely on a laptop cooler to keep it from overheating. The specs are way outdated, Core2Duo if you're wondering.

TL;DR: Both seem like decent devices but I wouldn't be so quick to buy either just yet. It will be a while before the Duet hits the market. Depending on what you're going to college for you might need something stronger than the t100. Neither device will last 7yrs. You would end up buying a new device every 2-3years.

Don't know whether we will be wrong or right, but we can say that you can see an Android phone coming out of their company very soon. ( Nokia Normandy)

MS makes money on from Android sales, so I'm sure it isn't a big concern for them.
