I love modularity!


Off-topic (but relevant):

I have a Fujitsu P7230. I have a modular bay.

I swap out my optical drive for a second battery or filler.

And I took a thinkpad modular harddrive tray, dremeled it down to 7mm (was 9mm), attached Fujitsu optical drive connector and stuck in a 320gb 2.5" into my DIY tray. A big upgrade from my internal 40GB 1.8".

I also love the battery design. The main battery is easily removable, just a couple of slide locks. Then I have an external charger that they call a "digital charger" and I can charge my primary and modular battery with it (it has two connectors, charges in series).

I'm not getting a new laptop unless it sports modular design.
