The ATI Radeon HD 3200 is an integrated graphics card. Because the card is integrated, you cannot replace it with another card. It it built into the motherboard. So the answer to your question is no.

However, The Radeon HD 3200 is a very capable card, despite being integrated. It supports DirectX 10 and Pixel Shader 4.0. Not to say it could outdo most dedicated chips, but for an integrated card it is very good. For example, you could run Doom 3 on High graphics settings at about 29 fps. Very playable.

As a final note, I own a tx2z myself and I have never been so impressed with an integrated graphics card such as this. Most all of the games I play (Half-Life 2 and other games around that time) are playable at near maximum settings and resolutions. I've even run Enemy Territory: Quake Wars with the DirectX 10 renderer, at minimal settings of course, but the fact that it's playable at all is amazing.

Those Japanese toilets are available for purchase in America as well but usually only Japanese buy them and not many at that. The cell phone thing is true, they completely live off of it. The system of money and credit and the trend of PCs developed different in the West and Japan so I think that's why so much is integrated into mobile phone culture in Japan. For example, there's little square marks, like bar codes, but for phones, on all sorts of posters in Japan and if you use your cell's camera on it, it jumps you to the web page. The other thing I have yet to see in USA is unlocking the cell phone with your fingerprint. There are some devices to lock your PC like that but it never really got popular in America. Also, there are remote controls for everything and this has been true since I noticed it in the 80s, maybe longer. Remotes for things I rarely or never see in America. Example, in my uncle's car in the 80s, we'd sit in the back and control the radio with the remote. Or we can't use the air conditioning at my grandmother's house anymore because someone lost the remote.

Yes, you ABSOLUTELY need a license to export anything from the USA. The good news is that there are lots of GENERAL licenses that are applied by rule to daily situations, such as the license to take your own luggage with you on a vacation. It is, however, a rather narrow license and doesn't apply to anything otherwise restricted from export by a specific rule.

Similarly, your particular software or hardware may be restricted from export to certain places because of its sophistication, and you would need to have someone help you determine whether it falls into one or more categories that requires a specific license for your planned destination.

The potential fines are enormous, if you're exporting anything that has a potential "dual use" by a foreign operative.

No, sorry you can't. I'm not a Mac person but from what I've seen of them it doesn't look like they have removable video cards. Furthermore, like 90% of laptops you can't change the video card in. Sorry, if you want better graphics you'll have to get a new laptop.
