GBA SP vs. Micro

Before you ask, yes - I have a black DS Lite, but I still want a GBA system(s) to where I can link two via whatever means necessary and interact between games (mainly Pokemon); not to mention where I can play my DS and another system (whichever GBA) simultaneously - which I can do so well, and I still enjoy playing my GBA games.

Currently, I have two original GBAs - making the first scenario possible. However, I am sick of having to rely on my DS for backlighting, seeing as how the originals don't have one. Don't bother asking me to buy a light for the original - which do not perform to my standards, and poses a distraction when playing.

Also, I want a new system. I have lost trust in buying used systems, as I've had quite a few go out on me.

With that said, which do you think is better?

Hm, I have an SP and it works fine.
The SP has a battery life which is twice as long as the Micro and shares the charger with the DS so if you happen to lose yours or something you can use the DS one.
The only downside of the SP is the size which still isn't very big but it is significantly larger than the Micro.
In my opinion, I'd say for a gamer, the SP would be better, but for a casual gamer, maybe someone looking for design or portability over gaming, go with the Micro.
The Micro actually looks pretty awesome, I might consider investing in one!

the micro is my choice, its only downside would be the screen size and the fact that you can't find them anymore, at least not in my case.

You can find plenty of them on eBay; in fact, I'm watching a couple of them until their time is about up for the auctions.

But yeah, my main concern is linking compatibility for games like Ruby and Sapphire, although I appreciate your opinion(s).

I would say go for the SP. The Micro's screen is too small. The battery life is also longer, and you can protect the screen from scratches. Let's not forget the GmeBoy/Color backwards compatibility, which the Micro lacks. There is also the fact that it comes with a standard GBA EXT port, rather than that crappy Micro port that no one uses.

Let's see Advantages of a Micro and SP:

SP has Double Battery Life and is Rechargable

GBM is very convenient for hardcore travelers. But I am not one

SP can trade

GBM can not (I think)

SP is less wide

GBM is a bit wide

SP said "Let there be light" and what I saw... it was goood.

GBM is very easy to lose

SP is SQUARE. Squares are holy.

GBM is dead

I think I've made my points now...

Actually, the Micro can trade with its predecessors via Converter Connector - which solves my main problem.

By the way, the Micro is brighter than the SP. Also, I don't plan on playing any Game Boy Color and/or Game Boy original games.
