Just some specs and facts;
- My T135 with wifi enabled and bluetooth turned off gets a run-time of 7:30 thanks to the low power consumption of the SU4100 CPU. No marketing there; that is a real-world number. However, I think that the SU4100 is the most power-efficient CPU Toshiba offers, so if you get an AMD CPU, your battery life will suffer considerably.
- The T115 uses the same battery as my T135 so endurance should be similar
Both weigh under 4 pounds while the AA1 with the 6-cell battery is about 2.8 pounds and the 1410 is a hair over 3 pounds.
- The T115 is 11.3“x8.3”, the T135 is 12.7“x8.8”, the 10.1” Aspire One is 10.2“x7.3”, the Acer 1410 is 11.2“x8.0”, and all four are about 1” thick. The T135 may be a little too big, but I think that the extra inch on the 1410 and T115 aren’t that big a sacrifice for all of the other gains.
- The Aspire One is the least capable and the 1024×600 screen makes some things difficult; the other three all have 1366×768 screens. The AA1 also has the worst graphics chip, so photography, while possible, might be better done on something better.
- The AA1 can be found for under $300 while the 1410 seems to average ~$400. The Toshibas vary a bit based on where you get them and which specific model you get, but can be found for under $500 if you shop around.
However, I would hold out for Toshibas that have the SU4100 since the SU2700 and especially the AMD chips kind of suck. If you go with the 1410, the CPU choices are ones I am not 100% familiar with beyond knowing that they vary considerably in performance and power consumption (and therefore battery life).
As for the AA1, you get what you get there (only one CPU choice) and I leave it to you to decide if the loss of computing power and graphics ability is worth the $100 savings and the extra inch of width and depth.
And, of course, there are other options; those are just the ones that pop to mind since those were the main ones I was looking at before getting my T135; the “final contenders” for a small, powerful, inexpensive portable that could live away from an AC outlet all day.
