waiting for a new Mac to buy

As much as I would like to buy a new Mac, I guess I will have to wait another few months. Right now I am still stuck on my old PowerBook 15" with PowerPC chip, MacOS 10.4 and Classic, so I can run Hypercard. Hopefully, there wil be a new HyperCard soon, so I can finally switch to new hardware. But given the fact, that USB3, FireWire3200, WirelessUSB, eSATA and internal 3G communications are still missing from Apple´s lineup, I might use my old 15" PowerBook for another few months, eventually.
