I would like to see the following on the next family of iMacs (wishful thinking most likely.)
- user replaceable hard drive with no vendor lock in
- SATA 6.0Gbps and eSATA 6.0Gbps
- bring back jumbo frames for the P55 NIC (1500MTU max makes me sad)
- USB 3.0, >=5 ports, and slightly wider spaced as well
- if there's no Firewire 1600, then 2 Firewire 800 ports, or 1 Firewire 800 + 1 Firewire 400 even
- return of a front LED for system power (why did they take this off from the white Intels, even if it's tiny that'd suffice)
- option for an SSD drive + boot drive
- Radeon 58xx Mobility or nVidia 200m series graphics
- SDXC support for card reader
- proper Mini Displayport/HDMI in (ie. not needing to have the computer up and running to do so)
- MiniDisplayport/HDMI In and Out
- Blu-Ray drive (even if it's just a combo drive [BD read, DVD write,] I don't see BD burning as a big deal)
- possibly thicker design (thinner isn't always better, I'm finding on the i7 I have that if you do anything remotely CPU intensive, the power supply scorches at around 80c, this would allow for better cooling via more heatpipes/more fans, and allow for more devices internally
- option to remove speakers for better cooling and more devices (I'll keep dreaming, even though removing them would allow for bigger heatpipes or even a 2nd hard drive)
I'm one of those who can't stand the built in speakers on the iMacs. They are craptastic. I don't expect much for 'free' speakers, but I'm one of those who finds that those speakers are a lot of wasted space for something that could be doing more (another HD, more cooling for the CPU or GPU, another quiet fan, etc.)
